CVE-2026-764464.9 MED23.0%
——7A vulnerability in an API of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker to read specific files on the underlying operating system of an affected device.
This vulnerability is due to improper restriction of XML external entity references. An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to read specific files on the affected system that the underlying process has permission to access.1dCVE-2026-764274.9 MED26.7%
——8A vulnerability in the offline profiler feed service of Cisco ISE could allow an authenticated, remote attacker to read arbitrary files that are stored on an affected device.
This vulnerability is due to the parsing of attacker-controlled feed metadata with an XML parser that does not disable external entity resolution. An attacker could exploit this vulnerability by uploading a crafted offline feed package through the administrative interface. A successful exploit could allow the attacker to read arbitrary files from the file system and issue requests to internal systems from the affected device. To exploit this vulnerability, the attacker must have valid administrative credentials.1dCVE-2026-127527.1 HIG41.4%
——12IBM Business Automation Workflow containers and traditional is vulnerable to an XML external entity injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resource.1dCVE-2026-126677.1 HIG30.0%

——6Flowable flowable-engine through 8.0.0 contains an XML external entity injection vulnerability in ProcessDiagramLayoutFactory.parseXml() that fails to disable external entity resolution when parsing deployed BPMN resources. Attackers with process deployment privileges can embed DOCTYPE declarations with external entities in BPMN files to read arbitrary local files or trigger requests to internal network endpoints when diagram layout is computed.1dCVE-2026-132656.8 MED13.1%
