keycloak: org.keycloak.protocol.oidc: HTTP Parameter Pollution in OIDC redirect URI allows response parameter duplication - #GHI-604

A flaw was found in Keycloak, an open-source identity and access management solution. When a client application is configured to accept broad redirect Uniform Resource Identifiers URIs, a remote attacker can manipulate the authentication process by crafting a special web address. If a user clicks...

python-cryptography: Duplicate self-signed intermediates can cause exponential path-building

SummaryWhen resolving invalid certificate chains that include duplicate copies of self-signed certificates, the processing recursively invokes the same candidate, leading to an exponential blowup. Although the limitation that the chain depth cannot exceed a specified maximum depth prevents...

PYSEC-2026-3553 python-cryptography: Duplicate self-signed intermediates can cause exponential path-building

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the buildchaininner function. An attacker can cause excessive resource consumption by submitting a certificate chain containing duplicate self-signed intermediates, which lead...

Amazon Linux 2023 : valkey, valkey-devel (ALAS2023-2026-2011)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-2011 advisory. A use-after-free vulnerability exists in Valkey's TLS connection handling that can crash the server that can potentially lead to remote code execution. When TLS is enabled, the server keeps a...

CVE-2026-69249

CVE-2026-69249 affects python-cryptography prior to 49.0.0, where resolving invalid certificate chains with duplicate self-signed intermediates can explode in recursion, causing resource exhaustion DoS. The core issue is in the recursive build_chain_inner not de-duplicating previously analyzed ca...
