CESA-2024:3265 advisory.

  - It is possible for a user in a different organization from the owner of a snapshot to bypass authorization
    and delete a snapshot by issuing a DELETE request to /api/snapshots/<key> using its view key. This
    functionality is intended to only be available to individuals with the permission to write/edit to the
    snapshot in question, but due to a bug in the authorization logic, deletion requests issued by an
    unprivileged user in a different organization than the snapshot owner are treated as authorized. Grafana
    Labs would like to thank Ravid Mazon and Jay Chen of Palo Alto Research for discovering and disclosing
    this vulnerability. This issue affects Grafana: from 9.5.0 before 9.5.18, from 10.0.0 before 10.0.13, from
    10.1.0 before 10.1.9, from 10.2.0 before 10.2.6, from 10.3.0 before 10.3.5. (CVE-2024-1313)

  - A memory leak flaw was found in Golang in the RSA encrypting/decrypting code, which might lead to a
    resource exhaustion vulnerability using attacker-controlled inputs. The memory leak happens in
    github.com/golang-fips/openssl/openssl/rsa.go#L113. The objects leaked are pkey and ctx. That function
    uses named return parameters to free pkey and ctx if there is an error initializing the context or
    setting the different properties. All return statements related to error cases follow the return nil,
    nil, fail(...) pattern, meaning that pkey and ctx will be nil inside the deferred function that should
    free them. (CVE-2024-1394)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
