Title
AstronRPA through 1.1.6 Cross-Tenant Shared Variable Disclosure via get-batch-shared-var
Summary
AstronRPA through 1.1.6 contains a missing tenant authorization check in robot-service that allows authenticated users to read other tenants' shared variables via the get-batch-shared-var endpoint. Attackers can enumerate sequential shared variable IDs and decrypt all-users variables re-encrypted with their own tenant key to recover other tenants' credentials in plaintext.

Title
Open Source Social Network (OSSN) through 10.1 IDOR via Message Attachment Route
Summary
Open Source Social Network (OSSN) through 10.1 contains an insecure direct object reference vulnerability in components/OssnMessages/ossn_com.php that allows authenticated users to read other users' private message attachments. Attackers can request the /messages/attachment/{guid} route with sequential or guessed file GUIDs to retrieve attachments from private conversations without sender or recipient verification.

Title
temporal-proxy payload decryption is not bound to the request namespace
Summary
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.

Title
MOVO through 0.2.3 Authorization Bypass via Document Endpoints
Summary
MOVO through 0.2.3 contains an authorization bypass vulnerability in the chat-api document endpoints that allows authenticated users to access other users' stored objects by supplying arbitrary object paths. Attackers who know a target's object path can send it to /api/documents/fetch or /api/documents/save-blueprint to read private documents and overwrite presentation blueprints.

Title
Improper authorization in query resolvers for SQL-backed models in AWS Amplify API Category
Summary
Improper authorization in the query resolvers generated by @aws-amplify/graphql-index-transformer in AWS Amplify API Category before 3.1.2 might allow an authenticated remote user to read records owned by other users of the same application via crafted queries.
This issue has been addressed in @aws-amplify/graphql-index-transformer 3.1.2 https://www.npmjs.com/package/@aws-amplify/graphql-index-transformer/v/3.1.2 (included in @aws-amplify/data-construct 1.17.4 https://www.npmjs.com/package/@aws-amplify/data-construct/v/1.17.4 and @aws-amplify/graphql-api-construct 1.21.4 https://www.npmjs.com/package/@aws-amplify/graphql-api-construct/v/1.21.4 ). We recommend upgrading to the latest version ensuring any forked or derivative code is patched to incorporate the new fixes and then redeploying their backend.

Title
Social Media Auto Post & Scheduler <= 9.1.4 - Authenticated (Contributor+) Insecure Direct Object Reference to Sensitive Information Exposure
Summary
The Blog2Social – Social Media Auto Post & Scheduler plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 9.1.4. This is due to the b2s_ship_item and b2s_ship_item_reload_url AJAX handlers lacking per-object authorization on the postId parameter. This makes it possible for authenticated attackers with Contributor-level access and above to read the title and content of any post, including private and pending posts belonging to other users.

Title
CiviForm: Trusted-Intermediary IDOR discloses any citizen's name and email
Summary
CiviForm simplifies applications for government benefits programs by reusing applicant data across multiple benefit applications. Prior to 3.33.0, GET /admin/tiDash/editClientForm/:accountId verifies that the requester is a Trusted Intermediary but showEditClientForm performs a raw lookupAccount(accountId) without confirming that the citizen account belongs to the requester's trustedIntermediaryGroup. An authenticated Trusted Intermediary can enumerate accountId values and read the applicant display name, including the citizen's name and email address, for accounts outside the intermediary's group. This issue is fixed in version 3.33.0.

Title
Jexactyl: Free-billing order endpoint renews and unsuspends arbitrary servers by ID (missing ownership check)
Summary
Jexactyl is a customisable game management panel and billing system. From 4.0.0 until 4.0.5, the POST /api/client/billing/free/process endpoint accepts a client-controlled server_id and loads the server without restricting the lookup to servers owned by the authenticated account. On installations with billing enabled, an authenticated user can renew or unsuspend another tenant's billable server when its renewal_date is non-null and more than seven days away, even without a subuser relationship to that server. This issue is fixed in version 4.0.5.

Title
Contao: Improper access control in the preview links module
Summary
Contao is an Open Source CMS. From version 5.7.1 until 5.7.12, core-bundle/config/services.yaml registers the preview access voter as Contao\CoreBundle\Security\Voter\DataContainer\PreviewAccessVoter although the shipped class is PreviewVoter. Symfony therefore omits voter autoconfiguration and removes the private service, so PreviewVoter::hasAccess() never enforces ownership. A non-admin backend user with the preview_link module can list every tl_preview_link record, obtain signed share URLs created by other users, and use them to view unpublished pages with showUnpublished despite lacking page permission. The advisory does not establish editing or deletion of foreign links. This issue is fixed in version 5.7.12.

Mitigation
Architecture and Design
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Architecture and Design
Implementation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Architecture and Design
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
