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 Command and Scripting Interpreter (T1059); ranked in the top 14% 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 map to AC-3 (Access Enforcement) and SA-11 (Developer Testing and Evaluation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

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.

Vulnerability Data

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…

Mitigating Controls (NIST 800-53 r5) AI

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

Input validation directly neutralizes special path elements before pathname construction occurs.

Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

Least functionality restricts the file types and automatic processing capabilities the system will accept.

PR.PS-05 mostly match
prevents

Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.PS-01 partial match
prevents

Hardened configuration baselines can enforce allowed file types and processing rules.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
