Is BlockGlow — Per-block Custom CSS Safe to Use in 2026?
Generally Safe
Score 100/100BlockGlow — Per-block Custom CSS has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The static analysis of blockglow v1.1.7 reveals a generally strong security posture. The plugin exhibits excellent practices regarding SQL queries, utilizing prepared statements exclusively. Furthermore, a high percentage of output is properly escaped, and a reasonable number of nonce and capability checks are present. The absence of critical or high-severity taint flows, dangerous functions, external HTTP requests, and a minimal attack surface (zero entry points) are significant strengths.
However, the presence of file operations, even if not immediately flagged as problematic in the static analysis, warrants cautious consideration. While the data doesn't indicate any direct vulnerabilities related to these operations, any interaction with the file system can introduce potential risks if not meticulously handled. The plugin's vulnerability history is clean, with no recorded CVEs, which is a positive indicator of past security diligence. This, combined with the current positive static analysis, suggests a well-maintained and secure plugin.
In conclusion, blockglow v1.1.7 appears to be a secure plugin with robust security practices in place, particularly concerning data handling and access control. The clean vulnerability history further reinforces this assessment. The only area to remain observant about is the file operations, although no immediate threats are identified from the provided data.
