semgrep 1.152.0 on Python PyPI

1.152.0 - 2026-02-17

Hooks (for both Claude Code and Cursor) now pull custom rules from the registry (custom-rules-hooks)
Turned on DNS rebinding protection for the MCP server (dns-check)
Environment variables can now be passed to third-party package managers invoked as part of --allow-local-builds dependency resolution via the environment variable SEMGREP_LOCAL_BUILD_ENV, which accepts a JSON object with string keys and string values. (SC-3163)
Memory management policies
A memory policy defines how OCaml's garbage collector should be configured for
a scan. There are two initial policies: "aggressive", the current behaviour,
which trades longer scan times for lower memory use, and "balanced", which
finds a middle ground between reclaiming heap memory in short order while
limiting how often the garbage collector runs. The policy can be configured
via the --x-mem-policy CLI flag for the pro engine; this flag is unused in
the OSS engine. (engine-2055)
Added experimental support for the OpenFGA authorization language. Thanks to Alex Useche (@hex0punk) for the contribution! (gh-11347)

Allows case insensitive string comparisons using lower() and upper() like this:

- metavariable-comparison:
    metavariable: $VALUE
    comparison: upper(str($VALUE)) == "SEMGREP"

Blocking findings that are outputted in the CI output are now labelled as such. (#4394)

pro: There should be fewer FNs when the max number of fields to track per object
is reached. (code-9224)
Remove legacy combined symbol analysis computation and upload in favor of per-subproject symbol analysis (sc-3153)

pro: Improved accuracy of taint tracking through assignments, this will help
reduce FPs in some cases. (code-9220)
When receiving a 429 or 5xx from the Semgrep app, the CLI will wait for a
longer period of time before retrying the request, to spread out requests
during periods of app instability. (engine-2550)
