Title
LinkWarden: Server-Side Request Forgery (SSRF) in Link Creation via fetchTitleAndHeaders Function
Summary
Linkwarden is a self-hosted, open-source collaborative bookmark manager to collect, organize and archive webpages. Prior to version 2.13.0, a Server-Side Request Forgery (SSRF) vulnerability in the fetchTitleAndHeaders function allows authenticated users to make arbitrary HTTP requests to internal services due to insufficient URL validation that only checks for "http://" or "https://" prefixes. This issue has been patched in version 2.13.0.

Title
LinkWarden: Stored XSS via Client-Side Archive Upload (Unsanitized HTML served from same origin)
Summary
Linkwarden is a self-hosted, open-source collaborative bookmark manager to collect, organize and archive webpages. In versions 2.14.0 and prior, the archive upload endpoint (POST /api/v1/archives/[linkId]?format=4) accepts HTML files (text/html) without sanitizing JavaScript content. When the archive is later accessed via GET /api/v1/archives/[linkId]?format=4, the HTML is served with Content-Type: text/html from the Linkwarden origin, without any Content-Security-Policy header. This allows arbitrary JavaScript execution in the context of the authenticated Linkwarden sessio. At time of publication, there are no publicly available patches.

Title
Linkwarden Local File Inclusion Vulnerability
Summary
Linkwarden is a self-hosted, open-source collaborative bookmark manager to collect, organize and archive webpages. In version 2.10.2, the server accepts links of format file:///etc/passwd and doesn't do any validation before sending them to parsers and playwright, this can result in leak of other user's links (and in some cases it might be possible to leak environment secrets). This issue has been patched in version 2.10.3 which has not been made public at time of publication.

Title
Linkwarden Local File Inclusion Vulnerability
Summary
Linkwarden is a self-hosted, open-source collaborative bookmark manager to collect, organize and archive webpages. In version 2.10.2, the server accepts links of format file:///etc/passwd and doesn't do any validation before sending them to parsers and playwright, this can result in leak of other user's links (and in some cases it might be possible to leak environment secrets). This issue has been patched in version 2.10.3 which has not been made public at time of publication.
