Which packages are affected by GHSA-j8qw-mwmv-28cg?

GHSA-j8qw-mwmv-28cg affects the following packages: org.apache.solr:solr-core (Maven). Ecosystems affected: Maven.

How do I fix GHSA-j8qw-mwmv-28cg?

Update org.apache.solr:solr-core to 4.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-j8qw-mwmv-28cg is resolved across your whole dependency graph.

How do I detect GHSA-j8qw-mwmv-28cg in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.solr:solr-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-j8qw-mwmv-28cg if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-j8qw-mwmv-28cg?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-j8qw-mwmv-28cg can be triaged on real exposure rather than presence alone.

Is GHSA-j8qw-mwmv-28cg actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-j8qw-mwmv-28cg, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-j8qw-mwmv-28cg?

GHSA-j8qw-mwmv-28cg has an EPSS (Exploit Prediction Scoring System) score of 56.3%, placing it in the 99th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

What type of vulnerability is GHSA-j8qw-mwmv-28cg?

GHSA-j8qw-mwmv-28cg is classified as Path Traversal (CWE-22). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-j8qw-mwmv-28cg published, and has it been updated?

GHSA-j8qw-mwmv-28cg was published on May 17, 2022 and was last updated on November 30, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Directory traversal vulnerability in SolrResourceLoader in Apache Solr before 4.6 allows remote attackers to read arbitrary files via a .. (dot dot) or full pathname in the tr parameter to solr/select/, when the response writer (wt parameter) is set to XSLT. NOTE: this can be leveraged using a separate XXE (XML eXternal Entity) vulnerability to allow access to files across restricted network boundaries.
