CVE-2026-63075

Issue summary: When OpenSSL processes QUIC traffic from a peer that repeatedly sends ack-eliciting packets while not acknowledging ACK-only responses, the QUIC stack can retain ACK-only packet metadata for the lifetime of the connection. Impact summary: A remote peer that can complete a QUIC...

CVE-2026-63075 QUIC ACK-only Packet Retention Can Cause Memory Exhaustion

Issue summary: When OpenSSL processes QUIC traffic from a peer that repeatedly sends ack-eliciting packets while not acknowledging ACK-only responses, the QUIC stack can retain ACK-only packet metadata for the lifetime of the connection. Impact summary: A remote peer that can complete a QUIC...

CVE-2026-63075

OpenSSL's QUIC stack retains ACK-only packet metadata in its packet history for the full lifetime of a connection. Since ACK-only packets are not ack-eliciting, a remote peer that completes a QUIC handshake can force repeated ACK-only packet transmission (e.g., by sending numerous PING frames ) a...

CVE-2026-63074

Issue summary: The OpenSSL Certificate Management Protocol CMP caches additional certificates extraCerts sent in a CMP message, but never expunges them for instance if they are invalid. If a server reuses an OSSLCMPCTX frequently, this cache of extraCerts may grow unboundedly, and a malicious...

EUVD-2026-65481

Issue summary: Receiving a DTLS record for a future epoch while a handshake is in progress causes OpenSSL to buffer far more memory than the record itself requires. Impact summary: A peer can use a small amount of network traffic to make an OpenSSL DTLS endpoint retain a disproportionately large...

BIT-KEYCLOAK-2026-9799 Keycloak: keycloak: unauthorized access to resources via uma permission ticket bypass

A flaw was found in org.keycloak.authorization. An authenticated user with a granted User-Managed Access UMA permission ticket for one resource can exploit this by using a specific permission request prefix to bypass per-resource access control. This allows the user to gain unauthorized access to...

BIT-KEYCLOAK-2026-4634 Keycloak: keycloak: denial of service via excessive processing of openid connect scope parameters

A flaw was found in Keycloak. An unauthenticated attacker can exploit this vulnerability by sending a specially crafted POST request with an excessively long scope parameter to the OpenID Connect OIDC token endpoint. This leads to high resource consumption and prolonged processing times, ultimate...

BIT-KEYCLOAK-2026-4630 Keycloak: keycloak: unauthorized resource access and data modification via insecure direct object reference

A flaw was found in Keycloak. An authenticated client could exploit an Insecure Direct Object Reference IDOR vulnerability in the Authorization Services Protection API endpoint. By knowing or obtaining a resource's unique identifier UUID belonging to another Resource Server within the same realm,...

BIT-KEYCLOAK-2026-37981 Keycloak: org.keycloak.authorization: keycloak: information disclosure via broken access control in user lookup endpoint

A flaw was found in Keycloak. A broken access control vulnerability in the Account Resources user lookup endpoint allows a remote authenticated user, who owns at least one User-Managed Access UMA resource, to enumerate and harvest personally identifiable information PII for all realm users. By...

CVE-2026-12600

CVE-2026-12600 is a denial-of-service vulnerability in the JPEG2000 (JPX) decoder within a Poppler fork maintained by Innodata Labs . The flaw resides in JPXStream::readCodestream(), where attacker-controlled values from the SIZ segment (e.g., img.nComps) are used to allocate memory for tiles and...

CVE-2026-12600 Uncontrolled memory usage in Innodata Labs’ Poppler JPX decoder

Denial-of-service DoS vulnerability in the internal JPEG2000 JPX decoding implementation of the Poppler fork developed by Innodata Labs. When an application processes an untrusted PDF file containing specially crafted JPXDecode images, a remote attacker can cause uncontrolled memory consumption...
