package pkcs12: Authentication bypass in Decode functions
GHSA-mpwr-8vm7-h73f
- Affected
- Go software.sslmate.com/src/go-pkcs12 >= 0.6.0, < 0.7.2
- Fixed in
- 0.7.2· Vendor fix available
- Issue
- Decode, DecodeChain, DecodeTrustStore, and ToPEM can incorrectly accept PKCS#12 files which were encoded with the wrong password, due to a failure to reject excessively-short PBMAC1 keys. Users who decode PKCS#12 files from untrusted sources and rely on the password for authentication can be tricked into accepting malicious PKCS#12 files. Users who only decode PKCS#12 files from trusted sources are not affected. Thanks to Pavol Žáčik (Red Hat) and Alex Gaynor (Anthropic) for finding and reporting the same issue in OpenSSL (CVE-2026-34181).
Recommended action: Upgrade to 0.7.2 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
