Is Only WebP Uploads Safe to Use in 2026?
Generally Safe
Score 100/100Only WebP Uploads has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The "only-webp-uploads" plugin v1.0.1 demonstrates a generally strong security posture based on the provided static analysis. It effectively utilizes prepared statements for all SQL queries, implements nonce and capability checks for its entry points, and properly escapes the vast majority of its output. The absence of critical or high severity taint flows, along with zero known vulnerabilities in its history, further reinforces this positive assessment. The plugin also has a very small attack surface with no unprotected entry points detected.
However, there are a few minor areas for consideration. While the number of file operations (3) is small, it's always good practice to ensure these operations are handled with utmost care, especially when dealing with user-uploaded content. The presence of 2 AJAX handlers, though protected, does represent potential interaction points that require ongoing vigilance. The plugin's vulnerability history is clean, which is an excellent sign, but this indicates it has likely not been subjected to extensive, long-term scrutiny. Overall, this plugin appears to be well-developed with good security practices in place, but minor areas of vigilance remain.
