- Apache Abdera: all versions
- Apache Abdera cb5a3646fc8b2a620dba5bdde3a6b7a3753b1be2 or later
Description:
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.
