CRITICAL · CVSS 3.0 · EPSS 77.4% (pctl 100)
Patch early
A public exploit exists.
Description
The getUserzoneCookie function in Kaltura before 13.2.0 uses a hardcoded cookie secret to validate cookie signatures, which allows remote attackers to bypass an intended protection mechanism and consequently conduct PHP object injection attacks and execute arbitrary PHP code via a crafted userzone cookie.
