OAKlouds-bulletin_v3-2.0: Relative Path Traversal
CVE-2026-93468 is a high-severity relative path traversal vulnerability in OAKlouds-bulletin_v3-2.0 from HGiga, 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 107 as the first without the flaw, so updating OAKlouds-bulletin_v3-2.0 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.68% chance of exploitation within 30 days, higher than 53% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update OAKlouds-bulletin_v3-2.0 to 107 or a later version.
- Update OAKlouds-bulletin_v3-3.0 to 107 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
The OAKlouds developed by HGiga has an Arbitrary File Read vulnerability. Unauthenticated remote attackers can exploit Relative Path Traversal to read arbitrary system files.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Relative Path Traversal
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as.. that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- 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: yes, technical impact: partial).
