⚐ CORRECTEDWednesday, October 14, 2026 at 4:31 PM EDT

Correction (Oct 14): An earlier version said Adobe's Content Credentials update covered six CVEs, five of them certificate-validation flaws. Adobe's APSB26-163 bulletin fixes more than 30 vulnerabilities, the worst rated 8.6 by Adobe, and four of the six CVEs we listed are certificate-validation flaws.

→ All corrections
Adobe has released security bulletin APSB26-163 for its Content Credentials tools, fixing more than 30 vulnerabilities rated high and medium.
Adobe says it is not aware of exploits in the wild for any of the issues.
Three products are affected. The flaws impact the Content Credentials Rust SDK c2pa-v0.90.15 and earlier, C2PA Tool c2patool-v0.27.15 and earlier, and the Content Credentials JS SDK @contentauth/c2pa-web@0.13.4 and earlier.

Adobe rates the worst flaw 8.6. Adobe, the CVE numbering authority for its products, scores the server-side request forgery bug CVE-2026-95634 at 8.6 under CVSS 3.1. Most of the others, including CVE-2026-100118, CVE-2026-100121, CVE-2026-100122, CVE-2026-100123, CVE-2026-100135 and CVE-2026-95633, are rated 7.5. NVD is still analyzing most of the records.

Most issues allow security feature bypass. The bugs include improper certificate validation, improper input validation and improper verification of cryptographic signatures. Many of the 7.5-rated bypass flaws can be exploited over a network without authentication or user interaction to gain unauthorized write access. Others can cause an application denial of service, and one path traversal flaw allows arbitrary file system writes.
