CVE-2026-62290

Affected software/area: cert-manager in Kubernetes clusters (certificates and issuers as resources). Vulnerability: Between 1.18.0 and 1.19.6, and 1.20.3, Challenge resources under acme.cert-manager.io could be created by namespace users without admission validation, allowing attacker-controlled ...

CVE-2026-62290 cert-manager: Direct ACME Challenge resources can bypass Issuer DNS01 solver policy and use ClusterIssuer DNS credentials

cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and using those certificates. From 1.18.0 until 1.19.6 and 1.20.3, Challenge resources under acme.cert-manager.io can be created directly by namespace...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal via unvalidated workspace outputPath handling in WorkspaceConfigurationStorageService and BaseApiConsumerConfiguration during kiota client generate and kiota plugin generate. An attacker can make Kiota write generate...

google.golang.org/grpc/grpc-go: google.golang.org/grpc/authz: gRPC-Go: Authorization bypass due to improper HTTP/2 path validation

A flaw was found in gRPC-Go, the Go language implementation of gRPC. This vulnerability, an authorization bypass, is caused by improper input validation of the HTTP/2 :path pseudo-header. A remote attacker can exploit this by sending raw HTTP/2 frames with a malformed :path that omits the mandato...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...

CVE-2026-15043

A flaw was found in DBI::SQL::Nano, a mini-SQL engine for Perl. This vulnerability occurs because the engine incorrectly evaluates SQL operators for text comparisons, specifically inverting the logic for "less than or equal to" and "greater than or equal to" operations. This can lead to...

CVE-2026-61863

A flaw was found in ImageMagick. When processing a Tagged Image File Format TIFF image, a small memory leak can occur if the TIFF encoder is unable to create a temporary file. This can lead to a gradual consumption of system memory, potentially impacting the availability of the application...

CVE-2026-61859

A flaw was found in ImageMagick. A local attacker with low privileges can exploit a policy bypass vulnerability in the -script operation due to missing security policy checks. This allows the attacker to read files from paths that are otherwise disallowed by the configured security policy, leadin...

CVE-2026-61868

A flaw was found in ImageMagick. A remote attacker could exploit a memory leak in the YUV decoder when processing a specially crafted image file. Repeatedly triggering this flaw can lead to resource exhaustion, resulting in a denial of service for the application. Mitigation Do not process...

CVE-2026-61866

A flaw was found in ImageMagick. A memory leak vulnerability exists in the JNG JPEG Network Graphics encoder when the application fails to open a blob. A remote attacker could exploit this by providing specially crafted malformed JNG files, leading to resource exhaustion and a denial of service D...

CVE-2026-61865

A flaw was found in ImageMagick. When processing images, a memory leak can occur during the 'hough lines' operation if an internal process fails. This vulnerability could lead to a gradual depletion of system memory, potentially resulting in a denial of service DoS for the affected system...

CVE-2026-56375

A flaw was found in ImageMagick. This vulnerability, a memory leak in the ASHLAR coder, occurs when an image processing action fails. An attacker can exploit this by triggering failed actions, leading to the exhaustion of memory resources. This can result in a denial of service DoS, making the...
