21 Oct 2024 — Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Starting in version 1.14.0 and prior to versions 1.14.16 and 1.15.10, a policy rule denying a prefix that is broader than `/32` may be ignored if there is a policy rule referencing a more narrow prefix (`CIDRSet` or `toFQDN`) and this narrower policy rule specifies either `enableDefaultDeny: false` or `- toEntities: all`. Note that a rule specifying `toEntities: world` or `toEntities: 0.0.0.0/0` is insufficient, it mu... • https://github.com/cilium/cilium/security/advisories/GHSA-3wwx-63fv-pfq6 • CWE-276: Incorrect Default Permissions •

16 Aug 2024 — Cilium is a networking, observability, and security solution with an eBPF-based dataplane. In versions on the 1.15.x branch prior to 1.15.8 and the 1.16.x branch prior to 1.16.1, ReferenceGrant changes are not correctly propagated in Cilium's GatewayAPI controller, which could lead to Gateway resources being able to access secrets for longer than intended, or to Routes having the ability to forward traffic to backends in other namespaces for longer than intended.

15 Aug 2024 — Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Prior to versions 1.14.14 and 1.15.8, a race condition in the Cilium agent can cause the agent to ignore labels that should be applied to a node. This could in turn cause CiliumClusterwideNetworkPolicies intended for nodes with the ignored label to not apply, leading to policy bypass. This issue has been patched in Cilium v1.14.14 and v1.15.8 As the underlying issue depends on a race condition, users unable to upgrade... • https://github.com/cilium/cilium/security/advisories/GHSA-q7w8-72mr-vpgw • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

15 Aug 2024 — Cilium is a networking, observability, and security solution with an eBPF-based dataplane. In the 1.15 branch prior to 1.15.8 and the 1.16 branch prior to 1.16.1, Gateway API HTTPRoutes and GRPCRoutes do not follow the match precedence specified in the Gateway API specification. In particular, request headers are matched before request methods, when the specification describes that the request methods must be respected before headers are matched. This could result in unexpected behaviour with security This ... • https://github.com/cilium/cilium/security/advisories/GHSA-qcm3-7879-xcww • CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •

27 Mar 2024 — Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Users of IPsec transparent encryption in Cilium may be vulnerable to cryptographic attacks that render the transparent encryption ineffective. In particular, Cilium is vulnerable to chosen plaintext, key recovery, replay attacks by a man-in-the-middle attacker. These attacks are possible due to an ESP sequence number collision when multiple nodes are configured with the same key. Fixed versions of Cilium use unique ke... • https://docs.cilium.io/en/stable/security/network/encryption-ipsec • CWE-326: Inadequate Encryption Strength •
