SCA: security update for bugsink (GHSA-vp6q-7m36-pq3w)

medium Tenable Cloud Security Plugin ID 437999

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Bugsink is a self-hosted error tracking tool. In versions prior to 2.0.13, an unauthenticated attacker who
 can submit events to a Bugsink project can store arbitrary JavaScript in an event. The payload executes
 only if a user explicitly views the affected Stacktrace in the web UI. When Pygments returns more lines
 than it was given (a known upstream quirk that triggers with Ruby heredoc-style input),
 `_pygmentize_lines()` in `theme/templatetags/issues.py:75-77` falls back to returning the raw input lines.
 `mark_safe()` at line 111-113 is then applied unconditionally - including to those unsanitized raw lines.
 Since DSN endpoints are public by Sentry protocol, no account is needed to inject. The payload sits in the
 database until an admin looks at the event. Successful exploitation requires that the attacker to be able
 to submit events to the project (i.e. knows the DSN or can access a client that uses it), the Bugsink
 ingest endpoint is reachable to the attacker, and an administrator explicitly views the crafted event in
 the UI. Under those conditions, the attacker can execute JavaScript in the administrator’s browser and act
 with that user’s privileges within Bugsink. Version 2.0.13 fixes the vulnerability. (CVE-2026-27614)
