High technical severity; prioritise exposed affected systems while verifying vendor guidance.
Debian, ubuntu findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.
A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

Fix not verified** UNSUPPORTED WHEN ASSIGNED ** Improper Neutralization of Expression/Command Delimiters vulnerability in Apache Commons OGNL. This issue affects Apache Commons OGNL: all versions. When using the API Ognl.getValue, the OGNL engine parses and evaluates the provided expression with powerful capabilities, including accessing and invoking related methods, etc. Although OgnlRuntime attempts to restrict certain dangerous classes and methods (such as java.lang.Runtime) through a blocklist, these restrictions are not comprehensive. Attackers may be able to bypass the restrictions by leveraging class objects that are not covered by the blocklist and potentially achieve arbitrary code execution. As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as expression or command delimiters when they are sent to a downstream component.
An attacker operating through a network path may attempt exploitation without authentication after a user interaction. If successful, the issue may execute code or commands in the affected security context.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-146: Improper Neutralization of Expression/Command Delimiters.
