DOMPurify before 3.4.11 fails to clone the ALLOWED_ATTR allowlist when setConfig() is used with an uponSanitizeAttribute hook, allowing the hook to permanently mutate the shared allowlist. Attackers can register a hook that conditionally allows dangerous attributes like onerror for trusted elements, then submit untrusted content that inherits the polluted allowlist and executes event handlers as stored XSS.
DOMPurify 3.0.0 before 3.4.9 does not reset the retained Trusted Types policy when clearConfig() is called, so a DOMPurify instance reused across trust boundaries stays bound to a previously supplied TRUSTED_TYPES_POLICY. A later caller that requests RETURN_TRUSTED_TYPE output receives a TrustedHTML object created by the old (potentially unsafe) policy rather than a clean default, which can lead to script execution at a Trusted Types sink. Passing TRUSTED_TYPES_POLICY: null on the later call also does not clear the retained policy.
DOMPurify versions >=3.0.0 and before 3.4.8, when configured with SAFE_FOR_TEMPLATES together with a DOM output mode (RETURN_DOM, RETURN_DOM_FRAGMENT, or IN_PLACE), fail to strip template expressions (e.g. ${evil}, {{evil}}, <%evil%>) inside <template> element content. The final normalization/scrub pass (_scrubTemplateExpressions) uses a NodeIterator and node.normalize() that do not descend into template.content, so expressions that only form after adjacent text nodes merge survive sanitization. This bypasses SAFE_FOR_TEMPLATES and can allow a downstream template engine to evaluate attacker-supplied expressions. The string output path is not affected.
Bold Reports Standalone Report Designer before 14.1.12 contains a missing filepath validation vulnerability in its font processing feature that allows unauthenticated attackers to read arbitrary files from the server filesystem by supplying a crafted request. Attackers can exploit this path traversal weakness to disclose sensitive server files, including authentication credentials, enabling full unauthorized access to the application. The vulnerability is specific to the DataHub module, which was introduced in Bold Reports 6.3. Therefore, versions prior to 6.3 are not affected.

Bold Reports Standalone Report Designer before 14.1.12 contains a missing filepath validation vulnerability in its file upload functionality that allows authenticated attackers to traverse outside the intended directory by supplying a crafted filename. Attackers can exploit this path traversal weakness to execute arbitrary commands with high privileges on the server. The vulnerability is specific to the DataHub module, which was introduced in Bold Reports 6.3. Therefore, versions prior to 6.3 are not affected.
