Libcupsfilters provides a library, which implements common functions used in cups-browsed daemon and printing filters, and additional files as banner templates and character sets. The filters are used in CUPS daemon and in printer applications.Security Fix(es): libcupsfilters: cups-filters: libcupsfilters: CPU exhaustion via infinite loop in cfIEEE1284NormalizeMakeModel() (CVE-2026-64611) libcupsfilters: cups-filters: libcupsfilters: CUPS image filter process abort via malformed PNG (CVE-2026-64612) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A flaw was found in the must-gather component of Red Hat Advanced Cluster Management for Kubernetes. Certain ACM wrapper Custom Resources that embed Secret data are collected without redaction. When an administrator runs must-gather, credentials and tokens are captured in cleartext in the resulting archive, potentially exposing sensitive information to anyone with access to the archive.

A flaw was found in the must-gather component of Red Hat Advanced Cluster Management for Kubernetes. The cluster Proxy object is dumped in raw form, bypassing the oc inspect redaction that would normally sanitize sensitive fields. This exposes proxy basic-auth credentials in the must-gather archive, potentially disclosing sensitive authentication information to anyone with access to the archive.

A flaw was found in Red Hat Quay's Stripe billing webhook handler. The /webhooks/stripe endpoint at endpoints/webhooks.py accepts incoming JSON requests without validating the Stripe-Signature header, allowing an unauthenticated attacker to forge billing events. The endpoint is registered unconditionally, even when FEATUREBILLING is disabled. An attacker can forge charge.succeeded events to reset a namespace's build quota to the server-configured maximum and trigger unsolicited billing emails (invoice, payment-failed, subscription-change) to namespace administrators. The checkout.session.completed path calls stripe.SetupIntent.retrieve with attacker-controlled IDs, but subsequent mutations use values from Stripe's response rather than the attacker's payload. Impact is Medium-High for quay.io deployments with real Stripe integration and Low for self-hosted defaults using FakeStripe.

A flaw was found in Red Hat Quay's exported logs feature. An unauthenticated attacker with a valid file ID could download exported action logs without proper authorization. While file IDs are complex, they can be intercepted from plaintext email or webhook callbacks. This vulnerability leads to information disclosure, potentially exposing sensitive data such as usernames, email addresses, IP addresses, and action-specific metadata.

A flaw was found in Red Hat Quay. A user with FEATUREBUILDSUPPORT enabled and repository write access can exploit a Server-Side Request Forgery (SSRF) vulnerability within the build API. This allows the user to provide a malicious URL, causing the Quay builder to make requests to internal network addresses. Such an action could lead to the disclosure of sensitive internal information.

A flaw was found in Red Hat Quay's Stripe billing webhook handler. The /webhooks/stripe endpoint at endpoints/webhooks.py accepts incoming JSON requests without validating the Stripe-Signature header, allowing an unauthenticated attacker to forge billing events. The endpoint is registered unconditionally, even when FEATUREBILLING is disabled.

Impact is Medium-High for quay.io deployments with real Stripe integration and Low for self-hosted defaults using FakeStripe.

A flaw was found in Red Hat Quay's build API. The endpoints/api/build.py endpoint accepts an archiveurl parameter with only an http/https scheme check and no SSRF validation. The URL is stored and passed to the builder fetch path, allowing a user with FEATUREBUILDSUPPORT enabled and repository write access to make the Quay builder issue requests to internal network addresses. This is a distinct code path from CVE-2026-16910 (webhook/Slack notification SSRF) with different privilege requirements and impact profile.

A flaw was found in Red Hat Quay's JWT (JSON Web Token) validation for federated robot accounts and single sign-on (SSO) authentication. Multiple issues related to audience verification and the enforcement of azp and sub claims were identified. These flaws could allow an attacker with a validly-signed token from the same identity provider to bypass configured security restrictions. This bypass could lead to unauthorized access by circumventing intended audience, subject, or authorized-client limitations.

A flaw was found in Red Hat Quay's external LDAP authentication handling. When an LDAP referral is returned during authentication, the referral handler at data/users/externalldap.py:700 constructs a search filter using the raw usernameoremail input without applying escapefilterchars(), unlike the normal authentication path which correctly escapes the input. This allows LDAP filter metacharacters (, (, )) in the username to be injected into the referral path's search filter. While SCOPEBASE limits the search to a single DN (preventing directory enumeration) and a separate simplebinds password check prevents direct authentication bypass, an attacker could use this to perform user-existence oracle attacks at the referral DN and potentially influence which DN enters the password bind in multi-domain Active Directory environments.

A flaw was found in Red Hat Quay. An administrator of any repository, by knowing or guessing a target notification's Universally Unique Identifier (UUID), can read the notification configuration, including sensitive details like webhook URLs, Slack tokens, and email addresses. This vulnerability also allows them to trigger test notifications for another repository. This could lead to unauthorized information disclosure and potential misuse of notification services.

A flaw was found in Red Hat Quay. When the SECURITYSCANNERV4PSK (pre-shared key) is not set, a remote unauthenticated attacker can send POST requests to the security scanner notification endpoint. This allows the attacker to flood the notification queue and inject path traversal characters into Clair API URL paths. The primary consequence is worker resource exhaustion and blind path manipulation on the configured Clair host, potentially leading to a denial of service.

A flaw was found in Red Hat Quay's repository notification API endpoints. The GET and test-trigger endpoints in endpoints/api/repositorynotification.py look up notifications by UUID without verifying that the notification belongs to the repository specified in the URL path. An admin of any repository who knows or guesses a target notification's UUID can read the notification configuration (including webhook URLs, Slack tokens, and email addresses) and fire test notifications for another repository's notification. The DELETE and reset endpoints correctly scope by repository. Exploitation requires knowing a 128-bit notification UUID.
