Which packages are affected by GHSA-2v8p-fqpx-2q3w?

GHSA-2v8p-fqpx-2q3w affects the following packages: jxl-modular (crates.io). Ecosystems affected: crates.io.

How do I fix GHSA-2v8p-fqpx-2q3w?

Update jxl-modular to 0.11.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2v8p-fqpx-2q3w is resolved across your whole dependency graph.

How do I detect GHSA-2v8p-fqpx-2q3w in my crates.io dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for jxl-modular, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-2v8p-fqpx-2q3w if there is no patch (or I can't update yet)?

Stop feeding it untrusted input: reject or quarantine files and payloads from unverified sources until you can upgrade, restrict accepted formats to the ones you actually need, and run the parsing or decoding step in a least-privileged sandbox or short-lived worker so a crash or corrupted read cannot reach the rest of the process.

Is GHSA-2v8p-fqpx-2q3w actively exploited in the wild?

No public exploit code has been indexed for GHSA-2v8p-fqpx-2q3w yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

When was GHSA-2v8p-fqpx-2q3w published, and has it been updated?

GHSA-2v8p-fqpx-2q3w was published on July 2, 2026 and was last updated on July 2, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.

Description

Summary

Logic bug in decode_simple_table_slow may cause integer arithmetic overflow when decoding Modular image with certain kind of MA tree, which may panic with overflow-checks enabled.

Impact

Denial of service: any application passing untrusted JXL data to JxlImage::render_frame (or equivalent) can be crashed. Affects all builds with overflow checks enabled, which includes debug builds and any release build that sets overflow-checks = true in Cargo.toml or [profile.*].

No memory corruption is possible — the panic fires before any unsafe code is reached.
