CVE-2026-40044 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Pachno 1.0.6 contains a deserialization vulnerability that allows unauthenticated attackers to execute arbitrary code by injecting malicious serialized objects into cache files. Attackers can write PHP object payloads to world-writable cache files with predictable names in the cache directory, which are unserialized during framework bootstrap before authentication checks occur.. EPSS estimates a 0.48% chance of exploitation in the next 30 days.
