Neo4j Graph apoc plugins Partial Path Traversal Vulnerability
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Impact
A partial Directory Traversal Vulnerability found in apoc.log.stream function of apoc plugins in Neo4j Graph database.
This issue allows a malicious actor to potentially break out of the expected directory. The impact is limited to sibling directories. For example, userControlled.getCanonicalPath().startsWith("/usr/out") will allow an attacker to access a directory with a name like /usr/outnot.
Patches
The users should aim to use the latest released version compatible with their Neo4j version. The minimum versions containing patch for this vulnerability are 4.4.0.8 and 4.3.0.7
Workarounds
If you cannot upgrade the library, you can control the allowlist of the functions that can be used in your system

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.neo4j.procedure:apoc. 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 org.neo4j.procedure:apoc to 4.4.0.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-78f9-745f-278p 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 GHSA-78f9-745f-278p 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 GHSA-78f9-745f-278p. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-78f9-745f-278p in your dependencies?
O3 detects GHSA-78f9-745f-278p across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
