Descripción técnica

TypeBot is a chatbot builder tool. Versions prior to 3.17.0 expose a deprecated public upload endpoint at `GET /api/v1/typebots/{typebotId}/blocks/{blockId}/storage/upload-url` that accepts an attacker-controlled `filePath` and returns a presigned S3 `PUT` URL for that exact key. Because the endpoint only checks that the referenced typebot is public and that the referenced block is a file input block, an unauthenticated attacker who knows a valid public `typebotId` and `blockId` can request presigned upload URLs for arbitrary objects in the shared bucket, including `private/...` and other tenants' `public/...` paths. Version 3.17.0 fixes this issue.

———calibre is an e-book manager. Prior to 9.12.0, the calibre Content Server endpoint POST /book-update-annotations/{library_id}/{book_id}/{fmt} in src/calibre/srv/books.py omits needs_db_write=True, causing Router.dispatch() to skip ctx.check_for_write_access() before update_annotations() passes attacker-controlled JSON to db.merge_annotations_for_book(), which allows a readonly user or an anonymous user on an unauthenticated deployment to persist unauthorized book annotation changes. This issue is fixed in version 9.12.0.3h CVE-2026-156068.8 ALT

———The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.29.9. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level and above permissions, to reset the password of any user on the site, including administrators, leading to full account takeover and complete site compromise. Exploitation requires the attacker to hold a valid encrypted Current-User token obtained by accessing any Edit User form they are legitimately authorized to submit, which they then use as a known-plaintext base for the CBC bit-flipping forgery.4h CVE-2026-691156.5 MED

———OpenIM Server v3.8.3 contains a missing authorization vulnerability that allows any authenticated user to access admin-only management API endpoints by submitting POST requests with a regular user bearer token to /user/get_users, /user/get_all_users_uid, and /group/get_groups. Attackers can exploit the absent authverify.CheckAdmin() call in the GetPaginationUsers, GetAllUserID, and GetGroups handlers to enumerate all platform user accounts including userIDs, nicknames, and manager level flags, as well as all groups including private groups the user has never joined, exposing group names, owner IDs, and member counts.5h CVE-2026-187096.4 MED

———An issue in MongoDB Server could allow an authenticated user with direct network access to a shard to improperly commit or abort an in-progress prepared transaction, bypassing the intended transaction coordination process. This could result in cross-shard data inconsistency, cluster clock corruption, and violation of transaction atomicity guarantees.4h CVE-2026-187046.5 MED

—

———An issue in MongoDB Server's aggregation framework could allow an authenticated user with only read privileges to perform write operations against collections they should not be able to modify. This is due to an internal-use aggregation stage being reachable by external clients without an appropriate authorization check on its embedded operations.4h CVE-2026-691135.4 MED

—

———Cap v0.3.1 contains a broken access control vulnerability in the POST /api/video/comment endpoint that allows authenticated users to post comments on any private video without permission by supplying an arbitrary videoId in the request body. Attackers can inject comments into private video recordings belonging to other users, trigger comment notification emails to the video owner, and enumerate valid video IDs through response differences.7h
