CVE-2026-22789: WebErpMesv2 has a File Upload Validation Bypass Leading to RCE

HighCVSS 8.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 35/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.27% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: SMEWebify WebErpMesv2 1.19.
  • Severity is disputed: the assigning authority (CNA) scores it 5.4, NVD 8.8.

Low priority for now. Upgrade to SMEWebify WebErpMesv2 1.19 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

WebErpMesv2 is a Resource Management and Manufacturing execution system Web for industry. Prior to 1.19, WebErpMesv2 contains a file upload validation bypass vulnerability in multiple controllers that allows authenticated users to upload arbitrary files, including PHP scripts, leading to Remote Code Execution (RCE). This vulnerability is identical in nature to CVE-2025-52130 but exists in different code locations that were not addressed by the original fix. This vulnerability is fixed in 1.19.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
