Not enough EPSS history yet.
Chroma through 1.5.9 fails to validate tenant and database segments when resolving collections, allowing authenticated attackers to access collections from other tenants by knowing the collection identifier. Attackers can read, modify, and update records in foreign collections by issuing requests under their own tenant path, bypassing authorization checks.

CVE-2026-928934.3 MED—
——0A flaw was found in the foreman_ansible plugin's Ansible inventory API. The controller builds its host query using an unscoped Host.where call that does not enforce the search filter associated with the caller's view_hosts permission. An authenticated user whose host visibility is restricted by a permission filter can supply arbitrary host IDs within their organization and receive the full Ansible inventory for those hosts, including parameter values marked as hidden.1hCVE-2026-92611——
——0In Eclipse Ankaios versions 0.6.0 to before 1.0.4, `LogRule::matches` in the agent control-interface authorizer stops at the first wildcard pattern in a single rule instead of evaluating later entries, which can cause deny `LogRule` entries to be skipped and allow unauthorized access to another workload's logs.1hCVE-2026-814393.7 LOW—
——0Dell OpenManage Server Administrator, versions prior to 11.1.0.3, contains an Incorrect Authorization vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to Protection mechanism bypass.1hCVE-2026-928944.3 MED—
——0A flaw was found in the foreman_ansible plugin's Ansible override values API. The destroy action resolves the target LookupValue record by ID without verifying it belongs to an AnsibleVariable the caller is authorized to edit. An authenticated user with the edit_ansible_variables permission can delete any LookupValue by ID, including override values for Ansible variables outside their permission filter scope and override values belonging to Puppet smart class parameters.2hCVE-2026-784263.7 LOW—
——0The NeuVector JWT verifier accepts noncanonical Base64URL encodings of the same RSA signature field. An attacker holding a valid JWT that has not expired, but was logged out of NeuVector, can continue using the non-expired token with equivalent spelling of the RSA signature field until the token validity expires.2hCVE-2026-928018.8 HIG—
——0cc-connect through 1.5.0 fails to enforce per-user allowlist filtering in the onCardAction handler for Feishu interactive card callbacks. Attackers can dispatch agent commands by triggering card actions in admitted chats, bypassing the per-user access controls that protect the text message handler.15h
