CVE-2026-113582 (GCVE-0-2026-113582)

Vulnerability from cvelistv5 – Published: 2026-10-22 13:27 – Updated: 2026-10-22 20:08 Unsupported When Assigned

Title

Apache Abdera: XML external entity expansion in Atom document parsing

Summary

UNSUPPORTED WHEN ASSIGNED Improper restriction of XML external entity references in Apache Abdera allows an attacker to access sensitive data or make server-side requests when an application parses attacker-controlled XML with Abdera. This issue affects Apache Abdera: all versions. Apache Abdera is retired and no longer supported, so we do not plan to release a version that fixes this issue. Users are recommended to migrate to a maintained alternative. Applications that cannot migrate should ensure that untrusted XML cannot reach the affected Abdera parser or JDBC adapter parsing paths. Actively maintained downstream products may still be impacted if they include an affected Abdera artifact. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

GHSA-7WC2-GP9G-C8R6

Vulnerability from github – Published: 2026-10-22 15:32 – Updated: 2026-10-22 21:32

Details

This issue affects Apache Abdera: all versions.

Apache Abdera is retired and no longer supported, so we do not plan to release a version that fixes this issue. Users are recommended to migrate to a maintained alternative. Applications that cannot migrate should ensure that untrusted XML cannot reach the affected Abdera parser or JDBC adapter parsing paths. Actively maintained downstream products may still be impacted if they include an affected Abdera artifact.

NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
