XML External Entity (XXE) Vulnerability in SOAP Interface Allows External Entity Expansion

Published Oct 29, 2026 · Updated Oct 29, 2026 · Assigned by MON-CSIRT

Description

In openEQUELLA before 2026.1, the SOAP API parses XML supplied in the stopEdit operation with a parser that resolves external entities. This allows an attacker to read arbitrary files accessible to the openEQUELLA service or cause the server to issue requests to attacker-specified locations (SSRF).
