Should you act?
Critical and remotely reachable
No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- 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.

Prior to versions 5.1.10, 5.2.15, and 5.3.7 on their respective release lines, FunctionsBuilder::jsonValue() with PostgresDriver is vulnerable to SQL injection when user-controlled data is supplied to the jsonPath parameter. This issue is fixed in versions 5.1.10, 5.2.15, and 5.3.7.
From the GitHub advisory
Impact The FunctionsBuilder::jsonValue($field, $jsonPath) methods with the Postgres driver is vulnerable to SQL injection if user controlled data is supplied to the $jsonPath parameter.
Patches 5.1.10, 5.2.15, 5.3.7
