docassemble: Use of Incorrectly-Resolved Name or Reference

CVE-2024-27292 is a high-severity use of incorrectly-resolved name or reference vulnerability in docassemble from Jhpyle, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.4.97 as the first without the flaw, so updating docassemble to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 69.5% chance of exploitation within 30 days, which is in the top 0.63% of all scored CVEs.

Patch now

Exploitation in the next 30 days is more likely than not, according to EPSS.

What to do

  1. Update docassemble to 1.4.97 or a later version.
  2. Read the advisory on github.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
