✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Applications utilizing undici should implement an independent request deadline and ensure the response body is explicitly destroyed upon expiration. The bodyTimeout mechanism alone is insufficient to prevent resource exhaustion in this scenario. Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability. Workaround: Upgrade to undici 7.29.1 or 8.10.2 (or later), where the shared cache interceptor no longer stores or re-serves responses containing Set-Cookie. Where an immediate upgrade is not possible: use a private cache (type: 'private') for per-user responses instead of the shared cache; avoid caching responses that carry a Set-Cookie header; or, if your service itself acts as a shared cache in front of an untrusted origin, strip Set-Cookie from upstream responses before caching them. Workaround: Applications that do not use BalancedPool, or that use it without a custom function-valued connect/tls option, are not affected and require no action. As a workaround until packages are updated, avoid using BalancedPool for any connection that relies on custom TLS certificate validation (e.g. certificate pinning); use Client, Pool, or Agent instead, which are unaffected. The permanent fix is upgrading undici to 7.29.1 or later (7.x line) or 8.10.2 or later (8.x line). Workaround: Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible to undici 8.10.2 or later.
