CVE-2026-71194 (GCVE-0-2026-71194)
Vulnerability from cvelistv5 – Published: 2026-08-12 22:23 – Updated: 2026-08-13 13:32

EPSS
VEX
Summary
In OpenStack Designate before 22.0.2, the mDNS handler performs pool-blind lookups when resolving record queries and NOTIFY requests. When two zones with the same name exist across different pools, the lookup fails with a deterministic error, causing the handler to return REFUSED for all DNS queries through that path. The _handle_notify path is exploitable via a single unauthenticated UDP packet. This is independently reachable through the cross-tenant zone overlap described in a different recent CVE, and also affects legitimate same-tenant cross-pool configurations. BIND9 views do not mitigate this issue as mDNS is a shared service upstream of any view configuration.

CVE-2026-71193 (GCVE-0-2026-71193)
Vulnerability from cvelistv5 – Published: 2026-08-12 22:17 – Updated: 2026-08-13 13:35

EPSS
VEX
Summary
In OpenStack Designate before 22.0.1, zone creation checks (_is_subzone, _is_superzone, and the duplicate-zone DB constraint) are scoped to the target pool only. An authenticated user can bypass these checks by scheduling a zone to a different pool via the AttributeFilter scheduler, creating an overlapping zone that conflicts with another tenant's zone. This enables cross-tenant DNS hijack (redirecting traffic to attacker-controlled IPs) and DNS denial of service (NODATA responses). Exploitation requires a multi-pool deployment with AttributeFilter enabled in scheduler_filters, which is a non-default but documented and supported configuration for self-service tiering.

CVE-2026-71192 (GCVE-0-2026-71192)
Vulnerability from cvelistv5 – Published: 2026-08-05 05:05 – Updated: 2026-08-05 13:31

Summary
In OpenStack Swift through 2.38.0, the S3API middleware does not sanitize Swift-native control headers (X-Copy-From, X-Copy-From-Account) from S3 API requests when s3_acl=true. An
attacker can inject these headers into a signed PUT request targeting their own bucket, causing Swift to perform a server-side copy from another tenant's private object. The source object authorization is bypassed because the S3API middleware has already authorized the request against the destination. The attacker can read any object whose project_id, container name, and object name are known, regardless of the source object's ACLs or ownership. This requires the non-default s3_acl=true configuration.

Summary
In OpenStack Swift through 2.38.0, S3API middleware does not enforce that semantic x-amz-* headers are covered by the SigV4 signature on presigned URL requests. An attacker who obtains a presigned PUT URL can inject an unsigned X-Amz-Copy-Source header, causing Swift to perform a server-side copy from an arbitrary source object using the signer's authorization context. The attacker can read any object the signer has access to, provided the target project_id, container name, and object name are known. This affects all deployments using the default s3_acl=false configuration.

Summary
In OpenStack Swift through 2.38.0, the proxy server Accept header parser contains a regular expression vulnerable to catastrophic backtracking (ReDoS). The "qdtext" pattern (?:[^"]|\\.)* allows an unauthenticated remote attacker to send a crafted Accept header that causes exponential CPU consumption in the proxy worker. A payload of 32 backslash-character pairs exceeds 30 seconds of CPU time. No authentication is required. Repeated requests can exhaust all proxy worker threads, resulting in a complete denial of service.

Summary
In OpenStack Neutron before 28.0.2, the subnetpool onboarding API does not verify ownership of the target subnets. An authenticated user can onboard subnets from another project's shared network into their own subnetpool, mutating the victim's subnet state and altering L3 routing and address scope behavior for victim routers.

CVE-2026-50221 (GCVE-0-2026-50221)
Vulnerability from cvelistv5 – Published: 2026-06-23 17:03 – Updated: 2026-06-23 17:38
VLAI
EPSS
VEX
Summary
In OpenStack Swift before 2.37.2, proxy-server does not strip internal update headers (X-Container-Host, X-Container-Device, X-Delete-At-Host, X-Delete-At-Device) from client requests before forwarding them to object-servers. An authenticated user with write access can inject these headers to redirect container update requests to an attacker-controlled server, enabling server-side request forgery. The SSRF requests expose internal cluster metadata including storage policy indexes, partition mappings, device names, and when at rest encryption is enabled, cipher text and initialization vectors for the container-level encryption key. The attacker can also cause "ghost listings" in arbitrary containers via the shard-range redirect mechanism.

CVE-2026-50266 (GCVE-0-2026-50266)
Vulnerability from cvelistv5 – Published: 2026-06-04 16:18 – Updated: 2026-06-04 17:28
VLAI
EPSS
VEX
Summary
In OpenStack Neutron before 28.0.1, a project manager can create or update a port on a shared network owned by another project and set device_owner to a value that has "network:" at the beginning ("network:dhcp" for example). The default port RBAC policies incorrectly included PROJECT_MANAGER without requiring network ownership, allowing any project manager to obtain trusted network-service port behavior on shared networks. Depending on backend and deployment, this can bypass anti-spoofing and security group protections, enabling DHCP, MAC, or IP spoofing against other tenants on the shared network. This is a regression of CVE-2015-5240 (OSSA-2015-018).

CVE-2026-49299 (GCVE-0-2026-49299)

VLAI
EPSS
VEX
Summary
In OpenStack Neutron before 28.0.1, the tagging controller enforces plural policy action names on single-tag write operations while the defined policy rules use singular names. The mismatched names evaluate as allowed under the default policy, permitting a project reader to create and update tags on same-project resources. Deployments running Neutron 26.0.0 or later are affected.

CVE-2026-44394 (GCVE-0-2026-44394)
Vulnerability from cvelistv5 – Published: 2026-05-28 00:00 – Updated: 2026-05-28 19:43
VLAI
EPSS
VEX
Summary
An issue was discovered in OpenStack Keystone before 29.0.2. The Keystone federated token rescoping mechanism does not propagate the original token's expiry to the newly issued token. When a federated user rescopes a token via POST /v3/auth/tokens, the handle_scoped_token() function in the mapped authentication plugin returns response data without an expires_at value. The token provider falls back to issuing a token with a fresh default TTL. By rescoping repeatedly before each token expires, a user can maintain access indefinitely, bypassing operator-configured token lifetime policies. This is a variant of CVE-2012-3426. Only deployments using federated identity (SAML2, OpenID Connect) are affected.

CVE-2026-42999 (GCVE-0-2026-42999)

Summary
An issue was discovered in OpenStack Keystone before 29.0.2. The Keystone RBAC policy enforcer in enforce_call unconditionally merges the raw JSON request body into the policy enforcement dictionary via policy_dict.update(json_input.copy()), overwriting trusted target data that was previously set from database lookups. Because flask.request.get_json is called with force=True, this works regardless of Content-Type or HTTP method. Any authenticated user can inject arbitrary policy target attributes (e.g., user_id, project_id) into the request body to bypass RBAC checks and perform unauthorized operations on resources belonging to other users or projects. This was introduced in commit 5ea59f52 (Rocky/14.0.0).

Summary
An issue was discovered in OpenStack Keystone before 29.0.2. The Keystone application credential authentication plugin does not verify that the user supplied in the authentication request matches the owner of the application credential. An attacker can authenticate with their own application credential ID and secret while specifying a different user's name and domain in the request body. Keystone issues a token attributed to the victim user. The impersonated token is project-scoped and carries the intersection of the application credential's roles and the victim's actual roles on the project. This enables audit evasion, reading the victim's credentials, and acting as the victim within shared projects.

Summary
An issue was discovered in OpenStack Keystone before 29.0.2. When combined with an application credential impersonation vulnerability, an attacker with the member role on a project can escalate to admin by chaining unrestricted application credentials with Keystone trusts. The impersonated token carries the victim's identity, which passes the trustor validation check. Keystone then validates the delegated roles against the victim's actual role assignments in the database, not the roles on the requesting token. This allows the attacker to create a trust delegating the victim's admin role to themselves. The trust persists independently, and additional trusts and application credentials can be created to maintain access. All actions are logged under the victim's identity.

When combined with an application credential impersonation vulnerability, an attacker with the member role on a project can escalate to admin by chaining unrestricted application credentials with Keystone trusts. The impersonated token carries the victim\u0027s identity, which passes the trustor validation check. Keystone then validates the delegated roles against the victim\u0027s actual role assignments in the database, not the roles on the requesting token. This allows the attacker to create a trust delegating the victim\u0027s admin role to themselves. The trust persists independently, and additional trusts and application credentials can be created to maintain access. All actions are logged under the victim\u0027s identity."

Summary
In OpenStack Swift before 2.36.2 and 2.37.2, s3api middleware enters an infinite loop when processing a truncated aws-chunked PUT request body. The StreamingInput class repeatedly appends an empty buffer and re-reads, causing the proxy-server worker handling the request to become permanently unresponsive with increasing CPU and memory consumption. An authenticated attacker can systematically exhaust all proxy-server workers, resulting in denial of service. The defect was introduced in Swift 2.36.0.
