Release Notes

returntocorp/semgrep (returntocorp/semgrep)

v1.103.0

Compare Source

1.103.0 - 2025-01-15

Added

• pro: taint: Support for lambdas as callbacks.

  var tainted = source();
  
  function withCallback1(val, callback) {
      if (val) {
          callback(val);
      }
  }
  
  withCallback1(tainted, function (val) {
      sink(val); // finding !
  }); (code-7626)
  

• pro: python: Semgrep will now consider top-level lambdas like x below for
  inter-procedural analysis:

  x = lambda s: sink(s) # now we get a finding !
  
  x(taint) (gh-10731)
  

Changed

• Removed pip from the Semgrep Docker image. If you need it, you may install it by running apk add py3-pip. (saf-1774)

Fixed

• Python: Now correctly parsing files with parenthesized withs, like this:
  with (
  f() as a,
  g() as b,
  ):
  pass
  ``` (saf-1802)
• Semgrep will now truncate error messages that are produced when they are very long (saf-333)

v1.102.0

Compare Source

1.102.0 - 2025-01-08

Added

• Added pro-only support for parsing a dependency graph from package-lock.json v1 files (SC-1858)
• Added pro-only support for parsing a dependency graph from package-lock.json v2 and v3 files (SC-1991)
• The poetry.lock parser can now parse dependency relationships (ssc-1970)
• The Yarn.lock V1 and V2 parsers can parse dependency relationships. (ssc-1988)

Fixed

• The semgrep test and semgrep validate commands have been
  correctly documented as EXPERIMENTAL (in semgrep --help).
  Those commands are not GA yet and people should still
  use the semgrep scan --test and semgrep scan --validate (or
  the variants without the implicit "scan") commands (unless
  they want to experiment with getting results faster and are ok
  with incomplete coverage of the legacy semgrep --test
  and semgrep --validate). (experimental)
• Improve error handling for functionality ancillary to a scan (such as looking for nosemgrep comments and rendering autofixes) to reduce the likelihood of an unexpected error in such a component bringing down the entire scan. (saf-1737)
• Fix the behavior of semgrep when running into broken symlinks.
  If such a path is passed explicitly as a scanning root on the
  command line, it results in an error. Otherwise if it's a file discovered
  while scanning the file system, it's a warning. (saf-1776)
• Fixed another crash due to exception in lines_of_file. The code
  should now be more robust and not abort the whole scan when
  an out of bound line access happens during the nosemgrep analysis
  or when outputing the lines of a match. (saf-1778)
• Direct dev dependencies in yarn/npm lockfiles are now correctly marked as direct (sc-1996)

v1.101.0

Compare Source

1.101.0 - 2024-12-18

Added

• Improved pnpm-lock.yaml parsing. (gh-2663)

Changed

• Re-ordered some terminal output of semgrep ci to allow semgrep-app to block scans based on specific findings (SECW-2740)
• A few fields in the JSON output (e.g., "fingerprint", "metavars") require now
  the user to be logged in to see them.
  See https://semgrep.dev/docs/semgrep-appsec-platform/json-and-sarif#json
  for more information. (json)
• We're renaming semgrep OSS to Semgrep Community Edition.
  See https://semgrep.dev/blog/2024/important-updates-to-semgrep-oss/
  for more information. (rename)
• A few fields in the SARIF output (e.g., "fingerprints") require now
  the user to be logged in to see them.
  See https://semgrep.dev/docs/semgrep-appsec-platform/json-and-sarif#sarif
  for more information. (sarif)

Fixed

• pro: Improved inter-file tracking of tainted global variables. (code-7054)

• Python (pro-only): Taint now correctly tracks through calls to class methods
  within a class, via the cls parameter.

  So for instance, we would be able to determine a source-to-sink
  vulnerability in the following code snippet:

  class A:
    def foo(self, x):
      sink(x)
  
    @​classmethod
    def bar(cls):
      cls.foo(source)
  ``` (saf-1765)
  

• pro: Fixed bug when generating inter-procedural taint traces, that it could
  cause a call-step to be missing in the trace. (saf-1783)

• Restored the "rules" field in the SARIF output, even when logged out. (saf-1794)

v1.100.0

Compare Source

1.100.0 - 2024-12-12

Added

• Pro engine now correctly distinguishes overloaded Scala methods based on their
  arity and parameter types, e.g., foo(x: Int, y: String) vs. foo(x: String, y: Int). (code-7870)

Changed

• The minimum Python version for semgrep is now 3.9.
  We are dropping support for Python 3.8 (python)

Fixed

• pro: Fixed a bug in interprocedural index-sensitive taint analysis that caused
  false negatives when a function updated an arbitrary index, e.g.:

  var x = {};
  
  function foo(k) {
      x[k] = source();
  }
  
  function test(k) {
      foo(k);
      sink(x); // finding here!
  } (CODE-7838)
  

• Fixed bug affecting taint tracking through static fields when mixing accesses
  using the class name and using an instance object, e.g.:

  class C {
      static String s;
  }
  
  ...
  
          C o = new C();
          C.s = taint;
          sink(o.s); // finding ! (CODE-7871)
  

• No more RPC error when using --sarif with some join-mode rules.
  Moreover, regular rules without the 'languages:' field will be skipped
  instead of aborting the whole scan. (gh-10723)

v1.99.0

Compare Source

1.99.0 - 2024-12-05

Fixed

• Fix the date format used in --gitlab-sast option to match
  the spec and not use the RFC 3339.
  Thanks to Elias Haeussler for the fix. (saf-1755)

v1.98.0

Compare Source

v1.97.0

Compare Source

1.97.0 - 2024-11-19

Added

• Improved logic for interfile analysis in TypeScript projects using
  project references. (code-7677)
• Semgrep Pro engine now resolves method invocations on abstract classes. In
  addition to the existing resolution for interface method invocations, this
  change further enhances dataflow tracking accuracy for dynamic method
  invocations. (code-7750)
• Added the ability to validate temporary AWS tokens in the secrets product. (gh-2554)
• Poetry.lock & Pyproject.toml parsers can now handle multiline strings. (ssc-1942)

Fixed

• Improved error handling for some networking errors (e.g., premature server
  disconnection). In some cases this would previously cause a fatal error, but we
  should instead be able to recover in most instances (and now can). (code-7715)
• Target file selection in git projects: files containing special characters
  (according to git) are now scanned correctly instead of being ignored. (saf-1687)
• Swift: Ellipses and metavariable ellipses can now be used as function parameters in patterns. (saf-1721)
• Semgrep will no longer freeze when tracing is enabled and it has a low memory limit (saf-1722)
• osemgrep-pro: Autofix and nosemgrep now work properly (saf-1724)

v1.96.0

Compare Source

1.96.0 - 2024-11-07

Added

• The pro engine now handles duplicate function names in C. When duplicate
  functions are found, we assume that any of the duplicated functions could be
  called. For example, if the function foo is defined in two different files,
  taint errors will be reported for both instances:

  // "a/test.h"
  void foo(int x) {
      //deepruleid: dup-symbols
      sink(x);
  }
  
  // "b/test.h"
  void foo(int x) {
      //deepruleid: dup-symbols
      sink(x);
  }
  
  // "main.c"
  #ifdef HEADER_A
      #include "a/test.h"
  #else
      #include "b/test.h"
  #endif
  
  int main() {
      int x = source();
      foo(x);
  }
  ``` (code-7654)
  

Changed

• Reduced memory allocations while processing nosemgrep comments, improving memory use and time for scans with a large number of findings. (nosem-mem)

Fixed

• Optimized taint-mode (only in Pro) to scale better when there is a large number
  of matches of sources/propagators/sanitizers/sinks within a function. (flow-83)
• Fixed a bug in the supply chain scanner's gradle lockfile parser. Previously, semgrep would fail to parse
  any gradle lockfile which did not start with a specific block comment. Now, semgrep will parse gradle
  lockfiles correctly by ignoring the comment (allowing any or no comment at all to exist). (gh-10508)
• Exceptions thrown during the processing of a target should not fail
  the whole scan anymore (regression introduced in 1.94.0). The scan will
  have an exit code of 0 instead of 2 (unless the user passed --strict in which
  case it will exit with code 2). (incid-110)
• Fix exponential parsing time with generic mode on input containing many
  unclosed braces on the same line. (saf-1667)
• Fix regexp parsing error occurring during ReDoS analysis when encountering
  a character class starting with [: such as [:a-z]. (saf-1693)
• Fix in semgrep scan: anchored semgrepignore patterns for folders such
  as /tests are now honored properly. Such patterns had previously no
  effect of target file filtering. (semgrepignore-anchored-dirs)

v1.95.0

Compare Source

1.95.0 - 2024-10-31

Changed

• Remove deprecated --enable-experimental-requirements flag. Functionality has
  been always enabled since Semgrep 1.93.0. (ssc-1903)

Fixed

• osemgrep: Running osemgrep with the Pro Engine now correctly runs rules with proprietary languages (saf-1686)
• Fixed bug where semgrep would crash if --trace was passed (saf-tracing)

v1.94.0

Compare Source

1.94.0 - 2024-10-30

Fixed

• pro: taint-mode: Semgrep should no longer confuse a return in a lambda with
  a return in its enclosing function.

  E.g. In the example below the return value of foo is NOT tainted:

  function foo() {
      bar(() => taint);
      return ok;
  } (code-7657)
  

• OCaml: matching will now recognized "local open" so that a pattern like
  Foo.bar ... will now correctly match code such as let open Foo in bar 1
  or Foo.(bar 1) in addition to the classic Foo.bar 1. (local_open)

• Project files lacking sufficient read permissions are now skipped gracefully
  by semgrep. (saf-1598)

• Semgrep will now print stderr and additional debugging info when semgrep-core
  exits with a fatal error code but still returns a json repsonse (finishes
  scanning) (saf-1672)

• semgrep ci should parse correctly git logs to compute the set of contributors
  even if some authors have special characters in their names. (saf-1681)

v1.93.0

Compare Source

1.93.0 - 2024-10-23

Added

• Improved naming for Common JS module imports (require) in arbitrary
  expression contexts. Notably, in-line use of require should now be linked to
  the correct module. For instance, the pattern foo.bar should now match
  against require('foo').bar and taint is likewise similarily tracked. (code-7485)
• Secrets: semgrep ci output now includes a list of all secrets rules which
  generated at least one blocking finding (similar to Code) (code-7663)
• Added experimental support via --allow-dynamic-dependency-resolution for dynamic resolution of Maven and Gradle dependencies for projects that do not have lockfiles (in Semgrep Pro only). (gh-2389)
• Expanded support for pip requirement lockfiles is now available by default. Semgrep will now
  find any requirement.txt file and lockfiles in a requirements folder (**/requirements/*.txt).
  The existing experimental flag --enable-experimental-requirements is now deprecated and
  will be removed in a future release. (gh-2441)

Changed

• Removed support for Vue. The tree-sitter grammar has not been updated in 3 years,
  there was no community rules added and semgrep-vue is causing linking conflicts
  when compiling semgrep under Windows so just simpler to remove support for Vue.
  In theory, extract mode could be a good substitute to parse Vue files. (vue)

Fixed

• semgrep will now print exit codes if a segfault/OOM/other terminating signal happens in semgrep-core, or any of semgrep-core's child processes (saf-1646)
