The private keys of eight eMudhra/emSign intermediate CA certificates were disclosed as compromised on 2026-10-20 (CVE-2026-111943). - Require certifi >=2026.10.19 and ca-certificates >=2026.10.19, which remove the compromised emSign roots (the unaffected emSign Root CA - G1 is retained). - Require pip >=26.2.2: pip vendors its own certifi bundle and trusts it in addition to the system store, so older pip stays vulnerable. - Exempt these packages (plus pip) from the 7-day release cooldown in pixi.toml, otherwise the security releases would be blocked.
The temporary exemptions for certifi, ca-certificates and pip were only needed to let the eMudhra CA compromise security releases (CVE-2026-111943) through the 7-day release cooldown. They are no longer needed once those releases are older than the cooldown window, so the default protection is restored. The patched versions remain in pixi.lock: removing the exemptions does not re-resolve existing entries, it only applies to future updates.

Evidence
pixi.lockis unchanged by this PR (verified: no diff).Merge Danger
Door: two-way (restores the previous, more conservative behaviour; trivially revertable)
Blast Radius: future dependency updates only. Re-enabling the cooldown means newly released packages wait 7 days before being picked up, which is the intended protection against freshly-published (potentially compromised or broken) versions. Deliberate security updates will need a temporary exemption again, as in #204.
