CVE-2026-6570
LowCVSS 2.7Exploitation Probability (EPSS)
Low risk23th percentile - higher than 23% of all known CVEs
Summary
A security flaw was discovered in kodcloud KodExplorer up to 4.52. The initInstall function in /app/controller/systemMember.class.php, when manipulating the path argument, leads to authorization bypass. The attack may be initiated remotely and the exploit has been publicly released.
Risk Assessment
Authorization bypass may enable unauthorized access to installation functions and potentially application takeover. The public exploit increases the risk.
Recommendation
Update KodExplorer to a version later than 4.52 or restrict access to installation functions. Validate the path argument server-side.
Other vulnerabilities in KodExplorer
See all- CVE-2026-104081High
KodExplorer before 4.55 contains a path traversal vulnerability in the unzip_pre_name() function within app/function/helper.function.php, where a single non-recursive str_replace() sanitization pass can be bypassed using crafted filenames like "....//". Combined with PclZip's extract() call in KodArchive.class.php lacking the PCLZIP_OPT_EXTRACT_DIR_RESTRICTION option, an authenticated attacker can upload a malicious ZIP archive to overwrite arbitrary files, leading to admin account takeover and remote code execution.
- CVE-2026-6572Medium
A vulnerability was detected in Collabora KodExplorer up to 4.52 in /app/controller/share.class.php (fileUpload endpoint) due to improper authorization when manipulating the fileUpload argument. Remote exploitation is possible but requires high complexity. The exploit has been publicly disclosed and the vendor did not respond.
- CVE-2026-6571Medium
A weakness has been identified in kodcloud KodExplorer up to 4.52. Affected by this vulnerability is the function roleGroupAction of the file /app/controller/systemRole.class.php.
