Last modified

CVE-2026-82376 is a high-severity vulnerability rated 7.7/10 on the CVSS scale. 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. EPSS estimates a 0.30% chance of exploitation in the next 30 days.
