ldap3_proto has LDAP Filter stack exhaustion
Real-World Exposure
ldap3_protoReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
Impact
LDAP queries are not validated for depth, which can cause the parser (both PEG and ASN) to exhaust the stack. This may cause a denial of service in applications that process queries.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ldap3_proto, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update ldap3_proto to 0.7.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qcxq-75wr-5cm8 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-qcxq-75wr-5cm8 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-qcxq-75wr-5cm8. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
