Technical description

Lychee is a free, open-source photo-management tool. Prior to 7.6.3, GET /api/v2/Zip authorizes album and photo archives through AlbumPolicy::canDownload() and PhotoPolicy::canDownload() without first enforcing AlbumPolicy::canAccess(). For a public, password-protected album with grants_download enabled, an unauthenticated attacker who knows the shared album identifier can download a ZIP archive without supplying the password or unlocking the album, even though browsing endpoints deny access. The archive exposes the album's photos and can include full-resolution originals and associated metadata when grants_full_photo_access is enabled. This issue is fixed in version 7.6.3.

———La Suite Docs through 6.0.0 contains an authorization bypass vulnerability that allows authenticated users to write comments into threads of documents they cannot access. Attackers who know a thread UUID can route a POST comment request through their own document's resource_id, inserting comments into another document's thread without access.7h CVE-2026-108126—

———temporal-proxy 0.2.0 through 0.8.0 does not bind encrypted payloads to the namespace they were encrypted for. When payload encryption is enabled, the proxy chooses the decryption key by an identifier stored in the payload rather than by the namespace of the request, and nothing in the ciphertext records that namespace. A caller whom the proxy authorizes only for namespace B, and who has obtained an encrypted payload from namespace A, can therefore have the proxy decrypt it. In 0.8.0, the caller can submit the payload to the codec server's /decode endpoint. In every affected version, a caller who can also write to namespace B on the Temporal server directly can place the payload there and read it back through the proxy. This holds whether namespaces share the default key or each has its own, because a single proxy holds every key it is configured with. The issue does not give the attacker encrypted payloads they could not already obtain, and does not allow encrypted payloads to be modified.7h CVE-2026-1030835.4 MED

———NL Portal Backend Libraries provide backend components for Dutch government portals that interact with residents, customers, suppliers, and partner organizations. Prior to 3.0.3, both the getDocumentContent GraphQL query and GET /api/documentapi/{documentapi}/document/{documentId}/content REST route allow any authenticated portal user to retrieve a document without checking ownership of or another authorized relationship to it. A user with a valid login and another person's document identifier can read that document's contents, which may include sensitive personal information. Document identifiers are random and difficult to guess, but they can leak through other channels. This issue is fixed in version 3.0.3.8h CVE-2026-1103816.3 MED

———EspoCRM is an open source customer relationship management application. Prior to 10.0.3, a user with email-template edit access and mass-email sending access can reference restricted record fields in a template because the renderer stops filtering those fields when per-user ACL application is disabled. The same behavior affects group email auto-replies when a regular user can edit the selected template, even though an administrator controls the group email. Rendered messages can disclose restricted user fields. This issue is fixed in version 10.0.3.10h
