CVE-2026-2863 — A flaw has been found in feng_ha_ha/megagao ssm-erp and production_ssm up to 4288d53bd35757b27f2d070057aefb2c07bdd097
A flaw has been found in feng_ha_ha/megagao ssm-erp and production_ssm up to 4288d53bd35757b27f2d070057aefb2c07bdd097. The impacted element is the function deleteFile of the file FileServiceImpl.java. This manipulation causes path traversal. The attack can be initiated remotely. The exploit has been published and may be used. Continious delivery with rolling releases is used by this product. Therefore, no version details of affected nor updated releases are available. This product is distributed under two entirely different names. The project was informed of the problem early through an issue report but has not responded yet.

Matched remediation archetype
Path traversal, unsafe upload, and file handling
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
- Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
- Review canonicalization and containment checks across supported operating systems and storage backends.
Remediate safely
- Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
- Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
- Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
