# CVE-2024-44902: ThinkPHP deserialization vulnerability

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 4.2% , percentile 91: FIRST’s model estimates a 4.2% chance of exploitation activity in the next 30 days, higher than 91% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes topthink/framework (Composer (PHP)) >= 6.1.3, <= 8.0.4, no fixed version listed . Check your lockfile, including transitive dependencies.
