CVE-2025-58782 — Apache Jackrabbit Core, Apache Jackrabbit JCR Commons: JNDI injection risk with JndiRepositoryFactory

Deserialization of Untrusted Data vulnerability in Apache Jackrabbit Core and Apache Jackrabbit JCR Commons. This issue affects Apache Jackrabbit Core: from 1.0.0 through 2.22.1; Apache Jackrabbit JCR Commons: from 1.0.0 through 2.22.1. Deployments that accept JNDI URIs for JCR lookup from untrusted users allows them to inject malicious JNDI references, potentially leading to arbitrary code execution through deserialization of untrusted data. Users are recommended to upgrade to version 2.22.2. JCR lookup through JNDI has been disabled by default in 2.22.2. Users of this feature need to enable it explicitly and are adviced to review their use of JNDI URI for JCR lookup.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 1.4% (30-day exploitation probability)+11
  • Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

  • Maven Org.apache.jackrabbit:jackrabbit-core: fixed in version 2.22.2 — github.com (GitHub Security Advisories)
  • Maven Org.apache.jackrabbit:jackrabbit-jcr-commons: fixed in version 2.22.2 — github.com (GitHub Security Advisories)

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Apache Software Foundation Apache Jackrabbit Core, Apache Software Foundation Apache Jackrabbit JCR Commons, Apache Software Foundation Jackrabbit…).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. Apply the fixed version or the patch documented under Remediation.
  4. Search available logs for exploit probes matching the vulnerability class (insecure deserialization), errors and authentication anomalies.

What should defenders know first?

CVE-2025-58782 is "Apache Jackrabbit Core, Apache Jackrabbit JCR Commons: JNDI injection risk with JndiRepositoryFactory", rated Medium. It affects Apache Jackrabbit Core (Apache Software Foundation); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 6.5 describes technical severity. EPSS 1.35% estimates the probability of exploitation in 30 days; neither replaces your asset context.
