CVE-2025-12764
HIGHCVE-2025-12764 is a high-severity (CVSS 7.5) CWE-90 vulnerability in pgadmin4. O3 Security confirms whether CVE-2025-12764 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
pgAdmin 4: LDAP injection vulnerability in LDAP authentication flow.
Real-World Exposure
pgadmin4Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
pgAdmin <= 9.9 is affected by an LDAP injection vulnerability in the LDAP authentication flow that allows an attacker to inject special LDAP characters in the username, causing the DC/LDAP server and the client to process an unusual amount of data DOS.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐍PyPI | pgadmin4 | all versions | 9.10 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pgadmin4. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update pgadmin4 to 9.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-12764 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 pinpoints whether CVE-2025-12764 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2025-12764. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2025-12764 in your dependencies?
O3 detects CVE-2025-12764 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
