Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

DIRAC versions 6.20.1 up to but not including 8.0.79, 8.1.0a1 up to but not including 9.0.22, and 9.1.0 up to but not including 9.1.10 have a pilot wrapper that downloads the second-stage pilot script over HTTPS with certificate verification disabled, and the checksum file comes over the same channel. An attacker who can intercept the connection, such as through DNS or routing changes at a grid site's network, could substitute code that runs in the pilot context with access to pilot credentials. Upgrade to 8.0.79, 9.0.22, or 9.1.10 as appropriate.
