Title
Kyverno 1.11.0 before 1.19.2 Memory Exhaustion via Notary Signature Decompression
Summary
Kyverno from 1.11.0 before 1.19.2 contains an unbounded decompression vulnerability in FetchSignatureBlob that allows attackers to exhaust memory by supplying highly compressed notary signature layers. Attackers who control registry referrers or signatures can publish small gzip layers that decompress beyond maxPayloadSize, causing admission controller OOM kills and denial of service.

Title
Kyverno 1.18.0 before 1.19.2 verifyImages Cache Signature Verification Bypass
Summary
Kyverno 1.18.0 before 1.19.2 contains a signature verification bypass in verifyImages because cached verification results are keyed by the image reference string (such as a tag) rather than bound to the verified digest, so cache hits skip signature and attestation checks. An attacker who can submit workloads and move a registry tag can warm the cache with a signed image, repoint the tag, and have Kyverno admit the workload and use mutateDigest to pin the unverified digest.

Title
Kyverno before 1.19.2 Cross-Namespace Resource Read via generate.clone
Summary
Kyverno before 1.19.2 contains a missing authorization vulnerability that allows namespaced Policy authors to read resources in other namespaces by templating generate.clone or cloneList namespace values. Attackers can annotate a triggering ConfigMap so the background-controller copies a victim namespace's sensitive ConfigMap into the attacker's namespace, enabling cross-tenant data disclosure.

Title
Kyverno before 1.19.2 Cosign Identity Check Bypass via Empty SAN Certificates
Summary
Kyverno before 1.19.2 contains an authentication bypass in matchCertificateData that skips verifyImages subject and subjectRegExp checks when the signing certificate has no Subject Alternative Name. Attackers holding a leaf certificate from a configured private trust root can omit the SAN, set the expected Fulcio issuer OID, and sign malicious images that are admitted despite signer pinning.

Title
Kyverno 1.17.0 before 1.19.2 Cross-Namespace Privilege Escalation via NamespacedMutatingPolicy
Summary
Kyverno from 1.17.0 before 1.19.2 contains a privilege escalation vulnerability that allows namespace-scoped tenants to modify resources in other namespaces through NamespacedMutatingPolicy targetMatchConstraints.expression CEL output lacking namespace checks. Attackers can emit a literal target such as another tenant's RoleBinding, which the cluster-wide background controller then mutates to add attacker subjects or alter Roles, NetworkPolicies, and ConfigMaps.

Kyverno 1.19.1 before 1.19.2 Namespace Isolation Bypass via APICall URLPath Query String
Summary
Kyverno from 1.19.1 before 1.19.2 contains a namespace isolation bypass in APICall Fetch() in pkg/engine/apicall/apiCall.go because path.Clean treats '?' as a path character, letting the namespace regex match segments inside the query string. Users who can create namespaced policies can supply a URLPath like /api/v1/nodes?x=/namespaces/default/ that passes validation while client-go requests the cluster-scoped endpoint, reading resources outside their namespace.

Title
Kyverno before 1.19.2 Denial of Service via Unbounded CEL Policy Evaluation Cost
Summary
Kyverno before 1.19.2 contains a denial of service vulnerability that allows namespace-scoped policy authors to exhaust CPU and memory by submitting CEL expressions evaluated without runtime cost limits. Attackers can create a NamespacedValidatingPolicy or NamespacedDeletingPolicy with nested map comprehensions over large ConfigMap fields to OOM-kill Kyverno pods and block cluster-wide admission.

Title
Kyverno before 1.19.2 Denial of Service via Nested Variable Substitution Loop
Summary
Kyverno before 1.19.2 contains a denial of service vulnerability in substituteVariablesIfAny that allows low-privileged users to hang the admission webhook via self-referential variable templates. Attackers can create resources whose annotations re-introduce the embedded policy variable, causing unbounded substitution loops that exhaust CPU and memory and block cluster-wide admission.
Severity
CWE
- CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Kyverno 1.17.0 before 1.19.2 Privilege Escalation via CleanupPolicy Context Loader
Summary
Kyverno from 1.17.0 before 1.19.2 contains an authorization bypass vulnerability that allows namespace admins to escape namespace confinement because the cleanup controller builds its context loader with a nil policy. Attackers can create a namespaced CleanupPolicy with apiCall or globalReference context entries to read cross-namespace Secrets and modify validatingwebhookconfigurations using the cleanup controller's ServiceAccount.

Title
Kyverno 1.11.0 before 1.19.2 Memory Exhaustion via Notary Signature Decompression
Summary
Kyverno from 1.11.0 before 1.19.2 contains an unbounded decompression vulnerability in FetchSignatureBlob that allows attackers to exhaust memory by supplying highly compressed notary signature layers. Attackers who control registry referrers or signatures can publish small gzip layers that decompress beyond maxPayloadSize, causing admission controller OOM kills and denial of service.

Title
Kyverno 1.18.0 before 1.19.2 verifyImages Cache Signature Verification Bypass
Summary
Kyverno 1.18.0 before 1.19.2 contains a signature verification bypass in verifyImages because cached verification results are keyed by the image reference string (such as a tag) rather than bound to the verified digest, so cache hits skip signature and attestation checks. An attacker who can submit workloads and move a registry tag can warm the cache with a signed image, repoint the tag, and have Kyverno admit the workload and use mutateDigest to pin the unverified digest.

Title
Kyverno before 1.19.2 Cross-Namespace Resource Read via generate.clone
Summary
Kyverno before 1.19.2 contains a missing authorization vulnerability that allows namespaced Policy authors to read resources in other namespaces by templating generate.clone or cloneList namespace values. Attackers can annotate a triggering ConfigMap so the background-controller copies a victim namespace's sensitive ConfigMap into the attacker's namespace, enabling cross-tenant data disclosure.

Title
Kyverno before 1.19.2 Cosign Identity Check Bypass via Empty SAN Certificates
Summary
Kyverno before 1.19.2 contains an authentication bypass in matchCertificateData that skips verifyImages subject and subjectRegExp checks when the signing certificate has no Subject Alternative Name. Attackers holding a leaf certificate from a configured private trust root can omit the SAN, set the expected Fulcio issuer OID, and sign malicious images that are admitted despite signer pinning.
