CVE-2026-77131

Exploitation requires the attacker to already be in control of the SYSSY project's API key.

MEDIUM 5.3EPSS 0.15%

Does this matter?

Lower severity and a low EPSS score (0.15%). Track it; it rarely justifies an emergency change on its own.

Description

When OpenSSL is unavailable on the server, the extension transmits TYPO3 system information in cleartext instead of encrypting it. Exploitation requires the attacker to already be in control of the SYSSY project's API key.
