OS Recovery tool: Unquoted Search Path or Element

CVE-2026-82155 is a high-severity unquoted search path or element vulnerability in OS Recovery tool from Dell, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 2.4.4 as the first without the flaw, so updating OS Recovery tool to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.38% 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 OS Recovery tool to 2.4.4 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

Dell OS Recovery tool versions, prior to 2.4.4, contain a use of Untrusted Search Path vulnerability. An unauthenticated attacker with local access could potentially exploit this vulnerability, leading to Command execution.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Unquoted Search Path or Element

The product uses a search path that contains an unquoted element, in which the element contains whitespace or other separators. This can cause the product to access resources in a parent path.

How developers prevent this class of flaw

  • Properly quote the full search path before executing a program on the system.
  • Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
