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).
