wordpress.org/plugins/multi-image-uploadThis plugin adds a meta box to upload multiple images for posts and pages.
Is Multi Image Upload Safe to Use in 2026?
Generally Safe
Score 85/100Multi Image Upload has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The 'multi-image-upload' v2.0 plugin exhibits a mixed security posture. While the absence of known CVEs and a generally clean vulnerability history are positive indicators, the static analysis reveals significant concerns. The presence of two 'unserialize' calls without clear sanitization is a major red flag, potentially leading to remote code execution if user-supplied data is unserialized. Furthermore, the fact that 100% of outputs are not properly escaped, coupled with two 'unserialize' calls, creates a strong possibility for Cross-Site Scripting (XSS) vulnerabilities. The limited attack surface and the presence of nonce and capability checks on identified entry points are strengths, but they do not mitigate the risks associated with insecure deserialization and output handling.
Key Concerns
- Dangerous function: unserialize used
- Output escaping: 100% not properly escaped
