Machine-written summary

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

Nextflow versions 25.09.2-edge through 26.04.1 save Seqera Platform login tokens to a file that is world-readable under the default umask. On multi-user hosts, any local user who can reach the victim's home directory can read the token and impersonate them on Seqera Platform. Upgrade to 25.10.6 or 26.04.3, then revoke any token stored earlier.

Written 3 Nov 2026.
