Medium technical severity with public exploit material referenced by a structured source; prioritise exposed affected systems while verifying vendor guidance.
Canonical’s release and source-package findings are shown separately from local repository availability.
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.

Patch availablePrism (aka PrismJS) through 1.29.0 allows DOM Clobbering (with resultant XSS for untrusted input that contains HTML but does not directly contain JavaScript), because document.currentScript lookup can be shadowed by attacker-injected HTML elements.
Prism (aka PrismJS) through 1.29.0 allows DOM Clobbering (with resultant XSS for untrusted input that contains HTML but does not directly contain JavaScript), because document.currentScript lookup can be shadowed by attacker-injected HTML elements.
Untrusted data can cross into a code-evaluation path and be interpreted as executable instructions.
An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

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.
A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.
CWE-94: Improper Control of Generation of Code ('Code Injection'). The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
