Description

An integer underflow exists in the DNS proxy component of the macOS NetworkExtension system extension shipped with Akamai Guardicore Platform Agent (GPA) for macOS, whereby if a UDP datagram shorter than 96 bytes that begins with a specific value is received, a subsequent size computation underflows to a near-SIZE_MAX value, causing an allocation failure and uncaught Objective-C exception that aborts the root system extension.

CVE-2026-96616
Authentication tokens issued by the E3's web management interface on login are given an expiration time far beyond any reasonable session lifetime, effectively making them non-expiring. A token obtained through interception or device compromise remains valid for authenticated access for an extended period.

CVE-2026-115424
A flaw was found in the OpenShift client oc. When extracting container image layers with oc image extract, the application fails to properly sanitize symbolic and hard link targets pointing to absolute paths or to sibling directories of the extraction destination. An attacker who supplies a malicious container image can exploit this vulnerability by embedding links, and a chained file entry, that reference locations outside the intended extraction directory. This allows the attacker to write attacker-controlled content to arbitrary locations on the host filesystem with the privileges of the user running the command, potentially leading to file modification outside the destination directory.

CVE-2026-115221
A flaw was found in FreeIPA. An improper authorization check allows an authenticated host to retrieve and revoke digital certificates assigned to other users or services. This issue occurs because FreeIPA verifies ownership solely by matching the host name to the certificate's subject Common Name (CN), without confirming actual ownership in the directory service. Consequently, an enrolled host can disrupt services by revoking certificates belonging to other entities.

CVE-2026-114620
Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.9.0, Authlib's RFC 9101 JWTAuthenticationRequest passes the unauthenticated, client-controlled request_uri parameter to the abstract get_request_object() hook before applying a destination or registration policy; the hook itself performs no network request, while the documentation demonstrates an unrestricted HTTP fetch. In deployments whose integrator implements that hook as an unrestricted outbound fetch, a remote attacker who knows a valid public client identifier can make the authorization server request internal, link-local, or otherwise unintended URLs and can distinguish fetch outcomes through different error responses and timing. Deployments whose custom hook already applies a secure allowlist, destination controls, and retrieval limits are not affected. The JWTAuthenticationRequest implementation in authlib/oauth2/rfc9101/authorization_server.py forwards request_uri to get_request_object() before an application-approved retrieval policy accepts the destination. This issue is fixed in version 1.9.0.

CVE-2026-114619
Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.9.0, OpenIDImplicitGrant.validate_authorization_request() checks the client-controlled raw request.payload.scope for openid after the parent grant has filtered allowed scopes into request.scope. A registered client permitted an ID token response type but not the openid scope can add openid to the request, obtain user consent, and receive a signed ID token containing the user's subject and allowed profile claims. Authorization code flow and deployments that allow openid for every client permitted an ID token response are not affected. In authlib/oidc/core/grants/implicit.py, OpenIDImplicitGrant.validate_authorization_request() checks request.payload.scope instead of the filtered request.scope. This issue is fixed in version 1.9.0.
