HP ImageDiags: Creation of Temporary File in Directory with Insecure Permissions

Published Updated By the CyberSecBulletin desk

CVE-2026-82346 is a high-severity creation of temporary file in directory with insecure permissions vulnerability in HP ImageDiags from HP, with a CVSS 4.0 base score of 7.0 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists version <5.0.0.36 as the first without the flaw, so updating HP ImageDiags to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.14% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update HP ImageDiags to <5.0.0.36 or a later version.
  2. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

A potential security vulnerability has been identified in the HP ImageDiags for versions prior to 5.0.0.36. The vulnerability could potentially allow a local attacker to escalate privileges due to insufficient access controls.

The underlying weakness: Creation of Temporary File in Directory with Insecure Permissions

The product creates a temporary file in a directory whose permissions allow unintended actors to determine the file's existence or otherwise access that file.

How developers prevent this class of flaw

  • Many contemporary languages have functions which properly handle this condition. Older C temp file functions are especially susceptible.
  • Try to store sensitive tempfiles in a directory which is not world readable -- i.e., per-user directories.
  • Avoid using vulnerable temp file functions.
