Which packages are affected by GHSA-r67p-m7g9-gxw6?

GHSA-r67p-m7g9-gxw6 affects the following packages: csv-sniffer (crates.io). Ecosystems affected: crates.io.

How do I fix GHSA-r67p-m7g9-gxw6?

Update csv-sniffer to 0.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r67p-m7g9-gxw6 is resolved across your whole dependency graph.

How do I detect GHSA-r67p-m7g9-gxw6 in my crates.io dependencies?

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

How do I mitigate GHSA-r67p-m7g9-gxw6 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.

How does O3 Security protect against GHSA-r67p-m7g9-gxw6?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-r67p-m7g9-gxw6 can be triaged on real exposure rather than presence alone.

Is GHSA-r67p-m7g9-gxw6 actively exploited in the wild?

No public exploit code has been indexed for GHSA-r67p-m7g9-gxw6 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.

What is the EPSS score for GHSA-r67p-m7g9-gxw6?

GHSA-r67p-m7g9-gxw6 has an EPSS (Exploit Prediction Scoring System) score of 1.2%, placing it in the 67th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-r67p-m7g9-gxw6?

GHSA-r67p-m7g9-gxw6 is classified as CWE-908 (CWE-908). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Real-World Exposure

1 pkg affected

🦀csv-sniffer

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

Affected versions of this crate passes an uninitialized buffer to a user-provided Read implementation (within fn preamble_skipcount()).

Arbitrary Read implementations can read from the uninitialized buffer (memory exposure) and also can return incorrect number of bytes written to the buffer. Reading from uninitialized memory produces undefined values that can quickly invoke undefined behavior.
