TeamDavid: Absolute Path Traversal
CVE-2026-54202 is a high-severity absolute path traversal vulnerability in TeamDavid from Tobit Laboratories, with a CVSS 4.0 base score of 8.5 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version Rollout 528 as the first without the flaw, so updating TeamDavid to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.45% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update TeamDavid to Rollout 528 or a later version.

Official description
Tobit Laboratories AG TeamDavid's Webbox is vulnerable to a path traversal vulnerability in the archive creation functionality. Because the archive path is user-controlled and insufficiently validated, an attacker can manipulate the input to traverse directories. This allows the creation of folders in arbitrary locations, including sensitive directories such as C:\Windows or for different users. This issue affects TeamDavid before Rollout 528. Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.

The underlying weakness: Absolute Path Traversal
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as /abs/path that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- 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.
- Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
