| Affected | 5.2.x **through 5.2.13** (also 5.1.x JSONB_PATH_QUERY. CakePHP 5.2.13. Fixed 5.2.15.

- **Notes:** CVE-2026-77635 CWE-89. Witness POCWitness77635. Requires PostgreSQL.

- `PostgresDriver quoteIdentifier into JSONB_PATH_QUERY`

POCWitness77635 in HTTP body and sql= contains the injected fragment.

- empty json path result without injection

**Do this first:** Update **CakePHP** to **5.2.15** (or 5.1.10 / 5.3.7). Advisory: [GHSA-fxf7-vhh8-7vpq](

- Re-run `CVE-2026-77635-Abraxas-Labs.py` against the patched build: the mapped witness must **not** appear.

- Confirm the vendor advisory / changeset in the deployed tree (see references).

- Disable or isolate the affected component.

- Hunt for the witness condition on production (new privileged users, unexpected files, injected rows — whatever this CVE's map names).

Target **only** ` (or the loopback you bound). Do not point this script at the internet.

Success is the **witness** above in the response body. Generic 200 HTML is not it.

Loopback stack used to reproduce. Official images unless a `Dockerfile` in this folder builds from source.

- [`lab/docker-compose.yml`](lab/docker-compose.yml)

Bind the vulnerable product tree to Compose if the YAML mounts a local directory (plugin zip / source tag from the version table). Publish nothing except `127.0.0.1`.
