propel/propel1 SQL injection possible with limit() on MySQLGHSA-7g7c-qhf3-x59p
CRITICALFix: propelorm/Propel#1054GHSA-7g7c-qhf3-x59p is a critical-severity (CVSS 9.8) remote code execution vulnerability in propel/propel1. A fix is available for propel/propel1 — see the affected versions and patch details below.
Real-World Exposure
propel/propel1Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
The limit() query method is susceptible to catastrophic SQL injection with MySQL.
For example, given a model User for a table users:
UserQuery::create()->limit('1;DROP TABLE users')->find();
This will drop the users table!
The cause appears to be a lack of integer casting of the limit input in either Criteria::setLimit() or in DBMySQL::applyLimit(). The code comments there seem to imply that casting was avoided due to overflow issues with 32-bit integers.
This is surprising behavior since one of the primary purposes of an ORM is to prevent basic SQL injection.
This affects all versions of Propel: 1.x, 2.x, and 3.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for propel/propel1, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update propel/propel1 to 1.7.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7g7c-qhf3-x59p is resolved across your whole dependency graph.
Workarounds
Constrain what reaches the vulnerable code: limit the size and shape of untrusted input, isolate the affected component in a sandboxed or least-privileged process, and enable the platform's memory-safety mitigations (ASLR, stack protector, hardened allocator) so an out-of-bounds access is more likely to fail closed than to be exploitable.
