# CVE-2026-77635: CakePHP: FunctionsBuilder::jsonValue() vulerable to SQL injection with PostgresDriver

**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?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.5% , percentile 41: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 41% of all scored CVEs (low). 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 cakephp/cakephp (Composer (PHP)) >= 5.3.0, < 5.3.7, fixed in 5.3.7 ; cakephp/cakephp (Composer (PHP)) >= 5.2.0, < 5.2.15, fixed in 5.2.15 ; cakephp/cakephp (Composer (PHP)) >= 5.1.0, < 5.1.10, fixed in 5.1.10 ; cakephp/database (Composer (PHP)) >= 5.3.0, < 5.3.7, fixed in 5.3.7 . Check your lockfile, including transitive dependencies.
