No CVSS score has been assigned to GHSA-rjr4-v43m-pxq6 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-rjr4-v43m-pxq6?

GHSA-rjr4-v43m-pxq6 affects the following packages: triton-vm (crates.io). Ecosystems affected: crates.io.

How do I fix GHSA-rjr4-v43m-pxq6?

Update triton-vm to 2.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rjr4-v43m-pxq6 is resolved across your whole dependency graph.

How do I detect GHSA-rjr4-v43m-pxq6 in my crates.io dependencies?

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

How do I mitigate GHSA-rjr4-v43m-pxq6 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is GHSA-rjr4-v43m-pxq6 actively exploited in the wild?

No public exploit code has been indexed for GHSA-rjr4-v43m-pxq6 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-rjr4-v43m-pxq6 published, and has it been updated?

GHSA-rjr4-v43m-pxq6 was published on January 21, 2026 and was last updated on February 22, 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

In affected versions of Triton VM, the verifier failed to correctly sample randomness in the FRI sub-protocol.

Malicious provers can exploit this to craft proofs for arbitrary statements that this verifier accepts as valid, undermining soundness.

Protocols that rely on proofs and the supplied verifier of the affected versions of Triton VM are completely broken. Protocols implementing their own verifier might be unaffected.

The flaw was corrected in commit 3a045d63, where the relevant randomness is sampled correctly.
