A fix is available — apply it.

The "tarfile" module would still apply normalization of AREGTYPE (\x00) blocks to DIRTYPE, even while processing a multi-block member such as GNUTYPE_LONGNAME or GNUTYPE_LONGLINK. This could result in a crafted tar archive being misinterpreted by the tarfile module compared to other implementations.

Frequently asked(5)

What is CVE-2025-13462?
CVE-2025-13462 is a low vulnerability published on March 12, 2026. The "tarfile" module would still apply normalization of AREGTYPE (\x00) blocks to DIRTYPE, even while processing a multi-block member such as GNUTYPELONGNAME or GNUTYPELONGLINK. This could result in a crafted tar archive being misinterpreted by the tarfile module compared to other implementations.
When was CVE-2025-13462 disclosed?
CVE-2025-13462 was first published in the National Vulnerability Database on March 12, 2026, with the most recent update on June 11, 2026. EchelonGraph re-ingests CVE updates from NVD on a 2-hour cycle, so this page reflects the latest published state.
Is CVE-2025-13462 actively exploited?
CVE-2025-13462 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 6.0% percentile likelihood of exploitation in the next 30 days — higher percentiles indicate greater predicted risk.
What is the CVSS score of CVE-2025-13462?
CVE-2025-13462 has a CVSS v3 base score of 3.3 (NVD). EchelonGraph synthesises NVD + CISA KEV + FIRST EPSS + GHSA into a combined EG score of 9.8.
How do I remediate CVE-2025-13462?
Patch to the fixed version published by the affected vendor. Where vendor advisories exist for CVE-2025-13462, EchelonGraph cross-links them in the Vendor Advisories panel below — those typically contain the canonical remediation steps, fixed version numbers, and any vendor-specific mitigations.
