n8n: Google Service Account Private Key Exposed in JWT Header

Impact When n8n was configured with a Google Service Account key, the full PEM private key was mistakenly placed in the JWT header's kid field which should only have held a key identifier. Since JWT headers were Base64-encoded rather than encrypted, the key could be recovered by anything that...

CVE-2026-64834

FFmpeg versions 0.6.3 through 8.1.2 contain an infinite loop vulnerability in the RTP/ASF demuxer within libavformat/rtpdecasf.c that allows remote attackers to cause denial of service by sending a crafted RTP/ASF stream. The rtpasffixheader function fails to validate a minimum chunksize when...

CVE-2026-64833 FFmpeg 0.7.1 - 8.1.2 Out-of-Bounds Read via S/PDIF Muxer spdifenc.c

FFmpeg versions 0.7.1 through 8.1.2 contain an out-of-bounds read vulnerability in the S/PDIF muxer that allows attackers to access memory beyond buffer boundaries by supplying a crafted DTS stream with a coresize value larger than the actual packet length. Attackers can exploit the missing bound...

CVE-2026-64833

FFmpeg versions 0.7.1–8.1.2 expose an out-of-bounds read in the S/PDIF muxer. The root cause is a missing bounds check in spdif_header_dts4, allowing a crafted DTS stream with core_size larger than the packet length to read memory beyond the packet buffer during S/PDIF re-muxing. As described, th...
