Medium technical severity with public exploit material referenced by a structured source; prioritise exposed affected systems while verifying vendor guidance. Verified remediation exists for at least one product or source, but 3 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Debian, ubuntu findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.
BlackTree has verified remediation for at least one product or source, but the relevant distribution still reports no fixed package for 3 affected package states shown here. Treat those rows as affected with no fix until that distribution publishes a fixed version.
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 availability varies by productA vulnerability was found in ESAPI esapi-java-legacy and classified as problematic. This issue affects the interface Encoder.encodeForSQL of the SQL Injection Defense. An attack leads to an improper neutralization of special elements. The attack may be initiated remotely and an exploit has been disclosed to the public. The project was contacted early about this issue and handled it with an exceptional level of professionalism. Upgrading to version 2.7.0.0 is able to address this issue. Commit ID f75ac2c2647a81d2cfbdc9c899f8719c240ed512 is disabling the feature by default and any attempt to use it will trigger a warning. And commit ID e2322914304d9b1c52523ff24be495b7832f6a56 is updating the misleading Java class documentation to warn about the risks.

The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as control elements or syntactic markers when they are sent to a downstream component.
An attacker operating through a network path may attempt exploitation without authentication or user interaction. 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.
CISA Vulnrichment records proof-of-concept exploitation in its SSVC data. BlackTree has not independently executed or validated exploit material.
CWE-138: Improper Neutralization of Special Elements. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as control elements or syntactic markers when they are sent to a downstream component.
