CVE-2026-81706: openssl_encrypt before 1.4.9 fails to prevent namespace collisions between own identities and contacts in Iden

Routine

MEDIUM 6.8WATCHLISTUPGRADE

CVE-2026-81706 is a medium-severity flaw (CVSS 6.8) affecting openssl encrypt. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

openssl_encrypt before 1.4.9 fails to prevent namespace collisions between own identities and contacts in IdentityStore, allowing attackers to create shadowed contact entries invisible until the corresponding own identity is deleted. When the own identity is deleted, the shadowed contact becomes visible and resolves to the attacker's keys, enabling silent key substitution for encrypted files.
