In Apache Batik 1.x before 1.10, when deserializing subclass of `AbstractDocument`, the class takes a string from the inputStream as the class name which then use it to call the no-arg constructor of the class. Fix was to check the class type before calling newInstance in deserialization.

Security readout for executives and security teams

Plain-English summary

Apache Batik versions before 1.10 could instantiate a class named inside serialized input while rebuilding certain document objects. The Apache notice describes this as an information disclosure issue. Risk is highest where applications accept or process untrusted serialized Batik-related data. The public bundle does not show active exploitation.

Executive priority

Treat this as a targeted dependency remediation item, not an emergency based on the provided evidence. Prioritize systems that process externally supplied files or serialized data and any internet-facing service embedding Batik before 1.10.

Technical view

During deserialization of an AbstractDocument subclass, Batik read a class name from the stream and invoked its no-argument constructor before confirming the class type. Apache fixed this by checking the type before newInstance. Affected versions are Apache Batik 1.0 through 1.9.1; 1.10 contains the fix.

Likely exposure

Organizations may be exposed through direct Apache Batik dependencies, OS packages, or third-party products bundling Batik 1.0 through 1.9.1. Exposure depends on whether the application deserializes Batik document objects from untrusted or attacker-influenced input.

Exploitation context

The provided sources do not report known active exploitation, and CISA KEV is false in the bundle. The credible attack context is deserialization of attacker-controlled data in applications using vulnerable Batik versions. Public sources label the issue as information disclosure, but operational exploitability details are limited.

Researcher notes

Evidence is strongest on affected range and fix direction. CVSS, CWE, and exploitation evidence are absent from the bundle. The Apache advisory title says information disclosure, while the CVE description centers on unsafe class instantiation during deserialization, so validate impact in each application context.

Mitigation direction

  • Upgrade Apache Batik to version 1.10 or later where feasible.
  • Apply relevant Debian, Ubuntu, Gentoo, or vendor package updates.
  • Identify third-party products that bundle vulnerable Batik versions.
  • Restrict or disable deserialization of untrusted Batik-related data where possible.
  • Check Apache and product-vendor guidance before applying compensating controls.

Validation and detection

  • Inventory direct and transitive Apache Batik dependencies.
  • Check deployed Batik versions are not 1.0 through 1.9.1.
  • Review OS package status against Debian, Ubuntu, and Gentoo advisories.
  • Confirm applications do not deserialize attacker-controlled Batik document objects.
  • Document any bundled Batik copies in commercial or internal software.
