The Wolfi security team deemed this advisory irrelevant for Wolfi:latest.
NVD Description
Note: Versions mentioned in the description apply only to the upstream nextcloud-server-31 package and not the nextcloud-server-31 package as distributed by Wolfi.
The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13, a brace pattern with a zero step value (e.g., {1..2..0}) causes the sequence generation loop to run indefinitely, making the process hang for seconds and allocate heaps of memory. Versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13 fix the issue. As a workaround, sanitize strings passed to expand() to ensure a step value of 0 is not used.
