CVE-2026-82376Apache Roller: XML external entity processing in trackback response parser
High 7.7
In plain English
A high-severity XML external entity in Apache Roller from Apache Software Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 22% of all known vulnerabilities).
Official description
Improper Restriction of XML External Entity Reference in Apache Roller 6.1.5 allows a user with entry-editing rights on a weblog to cause the server to parse an attacker-influenced trackback response with an XML parser that does not disable external entity resolution, leading to disclosure of files readable by the Roller process. The Trackback control is hidden in the standard UI, but its action remains directly reachable, and no non-default server configuration is required. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which removes the outbound trackback response parser.
