CVE-2026-24897
Published: 28 January 2026
Summary
CVE-2026-24897 is a critical-severity Path Traversal (CWE-22) vulnerability in Erugo Erugo. Its CVSS base score is 10.0 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 23.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and SI-10 (Information Input Validation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly addresses insufficient validation of user-supplied paths by requiring input validation to block path traversal and arbitrary file uploads.
Enforces access control policies to prevent low-privileged users from writing files to unauthorized locations such as the public web root.
Restricts user-supplied path inputs to safe formats, lengths, and characters to mitigate path traversal attempts.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Path traversal and unrestricted file upload in public-facing web application (Erugo) enables exploitation for RCE (T1190). Low-privileged access escalates to full server control via the vulnerability (T1068).
NVD Description
Erugo is a self-hosted file-sharing platform. In versions up to and including 0.2.14, an authenticated low-privileged user can upload arbitrary files to any specified location due to insufficient validation of user‑supplied paths when creating shares. By specifying a writable path…

within the public web root, an attacker can upload and execute arbitrary code on the server, resulting in remote code execution (RCE). This vulnerability allows a low-privileged user to fully compromise the affected Erugo instance. Version 0.2.15 fixes the issue.
Deeper analysisAI
CVE-2026-24897 affects Erugo, a self-hosted file-sharing platform, in versions up to and including 0.2.14. The vulnerability stems from insufficient validation of user-supplied paths during share creation, enabling an authenticated low-privileged user to upload arbitrary files to any specified location on the server. This flaw is classified under CWE-22 (Path Traversal), CWE-94 (Code Injection), and CWE-434 (Unrestricted Upload), with a CVSS v3.1 base score of 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
An attacker with low-privileged authenticated access can exploit this by specifying a writable path within the public web root, uploading and executing arbitrary code to achieve remote code execution (RCE). This grants full compromise of the Erugo instance, potentially leading to complete server control.
Erugo version 0.2.15 addresses the issue with a fix detailed in commit 256bc63831a0b5e9a94cb024a0724e0cd5fa5e38. Security practitioners should upgrade to this version immediately, as outlined in the GitHub Security Advisory GHSA-336w-hgpq-6369 and the v0.2.15 release notes.
