CVE-2026-59096

Dapr Sentry’s OIDC discovery endpoint can be poisoned: the issuer and jwks_uri in /.well-known/openid-configuration are derived from the request Host via an attacker-controlled X-Forwarded-Host when oidc-allowed-hosts is not configured, and the document is cached for one hour. This allows remote ...

Kerberos Hub private key (X-Kerberos-Hub-PrivateKey) leaked to cross-host redirect target due to redirect-following HTTP client without CheckRedirect

Summary The Kerberos Hub upload path sends the agent's Hub credentials in the custom X-Kerberos-Hub-PrivateKey and X-Kerberos-Hub-PublicKey request headers to the operator-configured Hub URL config.HubURI. The HTTP client used &http.Client in UploadKerberosHub is constructed without a CheckRedire...

libcurl: libcurl: Information disclosure due to persistent Referer header

A flaw was found in libcurl. This vulnerability causes the HTTP Referer header to persist even after it has been explicitly cleared. This can lead to the previous referrer string being unintentionally reused and sent in subsequent requests, potentially disclosing sensitive information to unintend...

kernel: netfilter: nft_inner: Fix IPv6 inner_thoff desync

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nftinner module. This vulnerability arises from an incorrect handling of IPv6 inner packet processing, where the transport header offset innerthoff becomes desynchronized from the Layer 4 protocol l4proto. A remot...

PYSEC-2026-689 OpenStack Nova Denial of service attack on the compute host

An issue was discovered in OpenStack Nova 15.x through 15.1.0 and 16.x through 16.1.1. By detaching and reattaching an encrypted volume, an attacker may access the underlying raw volume and corrupt the LUKS header, resulting in a denial of service attack on the compute host. The same code error...
