Is Regenerate Thumbnails Safe to Use in 2026?
Generally Safe
Score 100/100Regenerate Thumbnails has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The "regenerate-thumbnails" plugin, version 3.1.6, exhibits a generally strong security posture based on the provided static analysis. The plugin demonstrates excellent adherence to secure coding practices by avoiding dangerous functions, utilizing prepared statements for all SQL queries, and incorporating nonce and capability checks. Furthermore, the complete absence of external HTTP requests and file operations significantly reduces its attack surface. The lack of any recorded vulnerabilities in its history is a positive indicator of its stability and the development team's focus on security.
However, while the static analysis reveals a very low risk profile, a minor concern exists regarding the output escaping. With 16% of outputs not properly escaped, there is a potential, albeit likely low, risk of cross-site scripting (XSS) vulnerabilities if user-supplied data is involved in these unescaped outputs. The taint analysis showing zero unsanitized flows provides some reassurance, suggesting that even unescaped outputs might not be directly exploitable by malicious inputs. Overall, this plugin appears to be a secure choice, with the only notable area for potential improvement being the consistent application of output escaping.
