Is Mass Resizer Safe to Use in 2026?
Generally Safe
Score 100/100Mass Resizer has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The "mass-resizer" plugin v2.10.93 exhibits a strong security posture based on the provided static analysis and vulnerability history. The absence of any identified CVEs, both historically and currently unpatched, is a significant positive indicator. Furthermore, the plugin demonstrates good coding practices by utilizing prepared statements for all SQL queries and having a very high percentage of properly escaped output. The limited attack surface with zero identified entry points is also commendable.
However, the static analysis does reveal a few areas for concern. The most notable is the complete lack of nonce checks and capability checks on the identified entry points. While the current analysis shows zero unprotected entry points, the absence of these fundamental security mechanisms means that if any entry points were ever introduced or if the current count is an anomaly, they would be immediately vulnerable to unauthorized actions. The taint analysis also showed zero flows, which is good, but it also analyzed zero flows, suggesting a very limited scope of analysis for this metric.
Overall, "mass-resizer" v2.10.93 appears to be a relatively secure plugin, primarily due to its clean vulnerability history and adoption of secure coding practices for data handling. The main weakness lies in the fundamental security checks (nonces, capabilities) that are not present, creating a potential future risk if the attack surface expands or if the current analysis is incomplete. The plugin is well-maintained and avoids common pitfalls like raw SQL queries or unescaped output.
Key Concerns
- Missing nonce checks on entry points
- Missing capability checks on entry points
- Taint analysis covered very few flows
