Comparison of WordPress and Drupal security: Which is more reliable
Which CMS, WordPress or Drupal, is safer, and cannot be answered by impression, but should look at the public security records, patch processes, and ecosystem risk profiles of the two projects over the years. From the perspective of core data, neither of them is considered a 'vulnerability大户', what really determines the daily security level is the quantity and scale of third-party plugins and themes, the response speed of the maintenance party, and the operation and maintenance discipline of the site itself.
Core vulnerability data: quantity and scope
Sorted the security records of two projects by RTCamp, WordPress disclosed about 14 core vulnerabilities between 2023 and 2025; at the same time, Drupal released 22 security bulletins, of which 5 bulletins dealt with issues that were officially marked as not directly exploitable. Looking at the number of bulletins alone, it is easy to come to the false conclusion that 'Drupal is more dangerous', in fact, the two teams have different release habits for bulletins: Drupal publishes bulletins even for deep problems that are difficult to exploit directly, while the WordPress core is relatively conservative.
| Comparison dimensions | WordPress | Drupal | How to choose |
|---|---|---|---|
| Core vulnerabilities/announcements (2023 to 2025) | About 14 disclosed vulnerabilities | 22 security announcements, 5 not directly exploitable | Different scopes, don't just compare the total |
| Distribution of severity | Most are medium risk | Most are medium risk | Percentage of high-risk items to be concerned about |
| Risk concentration point | Large plugin and theme ecosystem | The core integration is high, the modules also have incremental risks | The number of third parties determines the exposure surface |
| Fix channel | Mature automatic update mechanism | The security team releases patches according to the公告 rhythm | See if it can be patched in time |
The distribution of severity is more important than the total
In the records on both sides, high-risk cases are少数, the vast majority of items stay in medium-risk. When evaluating your own risks, it is recommended to pay attention to only two types: one is the authentication bypass or remote code execution that can be triggered without authorization, and the other is the injection-type problems that can be exploited without background permissions. The statistics of quantity are an industry observation, whether or not to patch the patch on the day of the announcement is the actual safety line of the site.
The third-party ecosystem is the real risk surface
The WordPress plugin market is much larger than the Drupal module library, and the probability of being attacked also increases with the number of installations; although Drupal has a higher core integration and a lower proportion of dependence on third-party extensions, its modules also release independent security bulletins. Regardless of which side you choose, the more you install, the greater the risk surface, which is a common rule. The control methods are also common: clean up unused extensions, only keep plugins supported by active maintainers, and set change audit for extensions.
The security design philosophy of Drupal
Drupal has long been known for its strict security modeling, with a fine-grained permission system and content access control built into the core. The security team has a fixed pace of announcement disclosure (SA-CORE numbering system). The cost of this mechanism is a steep learning curve and high development costs, and small and medium-sized teams often need dedicated maintainers.
Enterprise-level selection evaluation list
- Check the recent announcements on both sides to confirm whether the high-risk items are related to your deployment form;
- Count the number of third-party extensions, estimate the monthly patch workload;
- Confirm whether you can enable automatic or semi-automatic updates, the median exploitation window is often counted in hours;
- Check the three basic defense lines of authentication, injection, and cross-site scripting to avoid treating platform security as site security.
By the way, if you don't want to rely on the platform not having many accidents for security, you can also choose to integrate the protection into the CMS of the system itself. For example, AnQiCMS is developed in Go language, with built-in JWT authentication, and has built-in defenses against SQL injection and XSS attacks, treating security as a core design goal rather than a patch item.
Common questions
Are there more vulnerabilities in WordPress than in Drupal?The core level is almost the same in magnitude (about 14 to 22, different in diameter), and most are medium-risk; the incremental increase in the plugin layer is the main source of risk for WordPress.
Can Drupal rest easy?No. It also continues to publish security bulletins, but the proportion of 'non-directly exploitable' announcements is higher, and the public perception is lower.
How should small and medium-sized teams choose?If there is no dedicated maintainer, either option requires reducing the number of plugins and updating discipline; if the long-term maintenance costs are taken into account, a lightweight CMS with a significantly lower memory usage than PHP-based systems is also an option.
What is the relationship between platform security and site security?The platform determines the basic defense line, and the site determines the configuration water level: weak passwords, directory permissions, missing backups, no platform can save it.
