Summary
vulnerability-lookup 2.16.0 contains an XSS vulnerability in bundle.py, comment.py, and user.py, which can be exploited by a user of a vulnerability-lookup instance who can add bundles, comments, or sightings. The vulnerability stems from insufficient sanitization of user-supplied input before rendering in templates and tables, allowing injection of arbitrary JavaScript.
Risk Assessment
An attacker can inject a malicious script that executes in other users' browsers, potentially leading to session theft, account takeover, or other client-side attacks.
Recommendation
Immediately update to a version that includes the fix. Also avoid using innerHTML and use safer DOM methods and input validation.
Other vulnerabilities in vulnerability-lookup
See all- CVE-2026-101041Medium
The account recovery (password reset) functionality in the vulnerability-lookup web application contains a TOCTOU race condition in the consumption of single-use recovery tokens. Two concurrent HTTP requests with the same valid token can both pass verification before either transaction commits, allowing both to set their own password on the target account. Additionally, a secondary defect in the same endpoint allows a valid recovery link to set an empty or trivially short password because form validation is not invoked.
- CVE-2026-73432Medium
SSRF vulnerability in the remote-instance synchronization functionality of Vulnerability-Lookup. Remote instance addresses were validated only for basic URL syntax before being stored, and the synchronization worker later dereferenced them without network-boundary restrictions, following redirects without revalidation. An authenticated administrator with admin:access permission could configure a remote instance pointing to internal, loopback, link-local, or cloud metadata services.
- CVE-2026-73431High
Vulnerability-Lookup has an authentication weakness in account activation and password recovery, where tokens are reusable and not purpose-bound. An attacker who obtains a valid link can repeatedly change the password and take control of the account.
- CVE-2026-73405Medium
An authorization bypass vulnerability in Vulnerability-Lookup allowed inactive or unconfirmed accounts to subscribe to Server-Sent Events (SSE) streams through the /pubsub/subscribe/<topic> endpoint. The token_required decorator only checked the X-API-KEY header against an existing user API key, without verifying the account's is_active and is_confirmed state. An attacker could create an account and immediately use the API key to access Pub/Sub topics that should only be available to active, confirmed users.
- CVE-2026-73374Medium
A stored cross-site scripting (XSS) vulnerability existed in Vulnerability-Lookup in the render_tag_badges Jinja filter used to display reference tags associated with vulnerability records. Values from containers.cna.references[].tags[] were directly interpolated into HTML badge elements and wrapped in markupsafe.Markup, bypassing Jinja's automatic HTML escaping. An authenticated user with permissions to create or modify vulnerability records could submit a crafted reference tag through the CNA API containing arbitrary HTML or JavaScript-capable markup.
Original NVD description (English source)
vulnerability-lookup 2.16.0 allows XSS in bundle.py, comment.py, and user.py, by a user on a vulnerability-lookup instance who can add bundles, comments, or sightings. A cross-site scripting (XSS) vulnerability was discovered in the handling of user-supplied input in the Bundles, Comments, and Sightings components. Untrusted data was not properly sanitized before being rendered in templates and tables, which could allow attackers to inject arbitrary JavaScript into the application. The issue was due to unsafe use of innerHTML and insufficient validation of dynamic URLs and model fields. This vulnerability has been fixed by escaping untrusted data, replacing innerHTML assignments with safer DOM methods, encoding URLs with encodeURIComponent, and improving input validation in the affected models.
