| CVE-2026-39944 | 1 Ceph | 1 Ceph | 2026-08-28 | 8.8 High |
| Ceph is an open-source distributed storage platform providing object, block, and file storage. In versions prior to 20.2.4 and 19.2.6, the RADOS Gateway (RGW) protects STS session tokens with an AES-128-CBC handler that provides no message authentication, allowing an attacker who holds any valid STS token to tamper with it undetected and escalate to full RGW administrative access. Because the ciphertext is unauthenticated, the attacker can perform a CBC bit-flip on the acct_type, perm_type, and is_admin fields of their own token, and a forged is_admin value triggers a global administrative override that bypasses all capability checks. The attack is reachable remotely over the RGW S3 endpoint and is a self-contained modification of a token the attacker already possesses, requiring no encryption oracle and no network observation. It requires only a single valid STS token, which need not carry any elevated privileges, with STS enabled. This issue is fixed in versions 20.2.4 and 19.2.6. | ||||
| CVE-2026-54330 | 1 Ceph | 1 Ceph | 2026-08-28 | 8.1 High |
| Ceph is an open-source distributed storage platform providing object, block, and file storage. In versions prior to 20.2.4 and 19.2.6, the Ceph Object Gateway (RGW) SigV4 handler does not reject requests that carry x-amz-* headers absent from the signed header set, allowing anyone holding a presigned URL to attach arbitrary unsigned x-amz-* headers that RGW will honor. AWS S3 requires every x-amz-* header on a SigV4 request to be signed and rejects requests bearing additional unsigned headers, but RGW validates only the headers listed in X-Amz-SignedHeaders and ignores any extra ones, so they take effect without being covered by the signature. By adding such headers to a presigned PUT URL, an attacker can grant themselves more capabilities than the URL's signer intended and escalate their privileges. This issue is fixed in versions 20.2.4 and 19.2.6. | ||||
| CVE-2026-50152 | 1 Ceph | 1 Ceph | 2026-08-28 | 9.1 Critical |
| Ceph is an open-source distributed storage platform providing object, block, and file storage. In versions prior to 20.2.4 and 19.2.6, the Monitor subscription handler fails to properly authorize access to the configuration-key store, allowing any CephX user with only `mon allow r` capabilities to read the entire store by sending a single crafted MMonSubscribe message. The config-key store holds sensitive secrets including OSD LUKS disk-encryption passphrases and, on cephadm-managed clusters, the SSH private key that cephadm uses to reach every host in the cluster. Because that key grants root on every node under the default cephadm configuration, a low-privileged read-only account can escalate to full cluster and host compromise. This issue is fixed in versions 20.2.4 and 19.2.6 | ||||
| CVE-2025-30156 | 1 Ceph | 1 Ceph | 2026-08-28 | 8.9 High |
| Ceph is an open-source distributed storage platform providing object, block, and file storage. In versions prior to 20.2.4 and 19.2.6, the CephX authentication protocol encrypts tickets with AES-128-CBC in an unauthenticated mode that uses a hard-coded initialization vector and no message authentication, allowing an attacker to forge credentials and gain cluster-wide access. Because the ciphertext is malleable and the monitor will encrypt attacker-chosen entity names, an attacker holding one low-privilege key and able to observe CephX traffic can use the monitor as an encryption oracle and splice ciphertext blocks into valid tickets for privileged entities such as Manager, MDS, and OSD. The same lack of authentication also lets an attacker with CephX permissions escalate privileges by flipping a single bit in a service ticket to set its allow_all field to true. This issue is fixed in versions 20.2.4 and 19.2.6. | ||||
| CVE-2025-52555 | 1 Ceph | 1 Ceph | 2026-04-15 | 6.5 Medium |
| Ceph is a distributed object, block, and file storage platform. In versions 17.2.7, 18.2.1 through 18.2.4, and 19.0.0 through 19.2.2, an unprivileged user can escalate to root privileges in a ceph-fuse mounted CephFS by chmod 777 a directory owned by root to gain access. The result of this is that a user could read, write and execute to any directory owned by root as long as they chmod 777 it. This impacts confidentiality, integrity, and availability. It is patched in versions 17.2.8, 18.2.5, and 19.2.3. | ||||
| CVE-2017-12155 | 2 Ceph, Redhat | 2 Ceph, Openstack | 2025-04-20 | N/A |
| A resource-permission flaw was found in the openstack-tripleo-heat-templates package where ceph.client.openstack.keyring is created as world-readable. A local attacker with access to the key could read or modify data on Ceph cluster pools for OpenStack as though the attacker were the OpenStack service, thus potentially reading or modifying data in an OpenStack Block Storage volume. | ||||
| CVE-2015-4053 | 2 Ceph, Redhat | 2 Ceph-deploy, Ceph Storage | 2025-04-12 | N/A |
| The admin command in ceph-deploy before 1.5.25 uses world-readable permissions for /etc/ceph/ceph.client.admin.keyring, which allows local users to obtain sensitive information by reading the file. | ||||
| CVE-2015-3010 | 2 Ceph, Redhat | 2 Ceph-deploy, Ceph Storage | 2025-04-12 | N/A |
| ceph-deploy before 1.5.23 uses weak permissions (644) for ceph/ceph.client.admin.keyring, which allows local users to obtain sensitive information by reading the file. | ||||
| CVE-2019-10222 | 3 Ceph, Fedoraproject, Redhat | 3 Ceph, Fedora, Ceph Storage | 2025-02-13 | 7.5 High |
| A flaw was found in the Ceph RGW configuration with Beast as the front end handling client requests. An unauthenticated attacker could crash the Ceph RGW server by sending valid HTTP headers and terminating the connection, resulting in a remote denial of service for Ceph RGW clients. | ||||
| CVE-2020-25677 | 2 Ceph, Redhat | 3 Ceph-ansible, Ceph Storage, Openshift Container Storage | 2024-11-21 | 5.5 Medium |
| A flaw was found in Ceph-ansible v4.0.41 where it creates an /etc/ceph/iscsi-gateway.conf with insecure default permissions. This flaw allows any user on the system to read sensitive information within this file. The highest threat from this vulnerability is to confidentiality. | ||||
| CVE-2020-1716 | 2 Ceph, Redhat | 2 Ceph-ansible, Ceph Storage | 2024-11-21 | 8.8 High |
| A flaw was found in the ceph-ansible playbook where it contained hardcoded passwords that were being used as default passwords while deploying Ceph services. Any authenticated attacker can abuse this flaw to brute-force Ceph deployments, and gain administrator access to Ceph clusters via the Ceph dashboard to initiate read, write, and delete Ceph clusters and also modify Ceph cluster configurations. Versions before ceph-ansible 6.0.0alpha1 are affected. | ||||
| CVE-2020-1700 | 4 Canonical, Ceph, Opensuse and 1 more | 4 Ubuntu Linux, Ceph, Leap and 1 more | 2024-11-21 | 6.5 Medium |
| A flaw was found in the way the Ceph RGW Beast front-end handles unexpected disconnects. An authenticated attacker can abuse this flaw by making multiple disconnect attempts resulting in a permanent leak of a socket connection by radosgw. This flaw could lead to a denial of service condition by pile up of CLOSE_WAIT sockets, eventually leading to the exhaustion of available resources, preventing legitimate users from connecting to the system. | ||||
| CVE-2018-1129 | 4 Ceph, Debian, Opensuse and 1 more | 10 Ceph, Debian Linux, Leap and 7 more | 2024-11-21 | N/A |
| A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol. Ceph branches master, mimic, luminous and jewel are believed to be vulnerable. | ||||
| CVE-2018-10861 | 4 Ceph, Debian, Opensuse and 1 more | 9 Ceph, Debian Linux, Leap and 6 more | 2024-11-21 | N/A |
| A flaw was found in the way ceph mon handles user requests. Any authenticated ceph user having read access to ceph can delete, create ceph storage pools and corrupt snapshot images. Ceph branches master, mimic, luminous and jewel are believed to be affected. | ||||
| CVE-2017-7519 | 2 Ceph, Debian | 2 Ceph, Debian Linux | 2024-11-21 | N/A |
| In Ceph, a format string flaw was found in the way libradosstriper parses input from user. A user could crash an application or service using the libradosstriper library. | ||||
