WordPress safety researchers at Patchstack printed their annual State of WordPress Safety whitepaper that confirmed a rise of excessive and significant severity vulnerabilities, highlighting the significance of safety for all web sites on the WordPress platform.
XSS Is Prime WordPress Vulnerability Of 2023
There are lots of sorts of vulnerabilities however the commonest by far was cross web site scripting (XSS) vulnerabilities, accounting for 53.3% of all new WordPress safety vulnerabilities.
XSS vulnerabilities usually happen as a result of inadequate “sanitization” of consumer inputs, which incorporates blocking any inputs that don’t conform to what’s anticipated. Patchstack shared that the Freemius framework, a third-party managed eCommerce platform, accounted for over 1,200 of all XSS vulnerabilities, representing 21% of all new XSS vulnerabilities found in 2023.
The Freemius Software program Growth Package (SDK) is used as a part of over 1,200 plugins which in flip is put in in over 7 million WordPress websites. This highlights the issue of provide chain vulnerabilities the place a part is used as part of a WordPress plugin which subsequently will increase the scope of a vulnerability past only one plugin.
Patchstack’s report defined:
“This 12 months we noticed as soon as once more how a single cross-site scripting vulnerability within the Freemius framework resulted in 1,248 plugins inheriting the safety vulnerability, exposing their customers to threat.
21% of all new vulnerabilities found in 2023 may be traced again to this one flaw. It’s very important for builders to decide on their stack rigorously and promptly apply safety updates when these change into obtainable.”
Extra Vulnerabilities Rated Excessive Or Crucial
Vulnerabilities are assigned a severity rating that corresponds to how disruptive a found flaw is. The scores vary from low, medium, excessive and significant.
In 2022 13% of recent vulnerabilities had been labeled as excessive or crucial. That share skyrocketed in 2023 to 42.9%, that means that there have been extra damaging vulnerabilities in 2023 that within the earlier 12 months.
Authenticated Versus Unauthenticated Vulnerabilities
One other metric that pops out within the report is the proportion of vulnerabilities that require no authentication (unauthenticated), that means the attacker doesn’t want any consumer permission degree with the intention to launch an assault.
Flaws that require an attacker to have a subscriber degree to admin degree permissions have a better bar for attackers to beat. Unauthenticated vulnerabilities don’t require that the attacker first get hold of a permission degree, which makes these sorts of vulnerabilities extra regarding as a result of they are often exploited by computerized assaults like with bots that probe a web site for the vulnerability then mechanically launch assaults.
Patchstack discovered that 58.9% of all new vulnerabilities required no authentication in any respect.
Deserted Plugins Spike As a Threat Issue
One other important trigger for vulnerabilities is the big quantity of deserted plugins. In 2022 Patchstack reported 147 deserted plugins and themes to WordPress.org and out of these 87 had been eliminated and the rest had been patched.
In 2023 the variety of deserted plugins exploded from 147 in 2022 to 827 plugins and themes in 2023. Whereas 87 weak deserted plugins had been eliminated in 2022, 481 had been eliminated in 2023.
Patchstack famous:
“We reported 404 of these plugins in a single day to attract consideration to the “zombie plugin pandemic” in WordPress. Such “zombie” plugins are parts that appear secure and up-to-date at first look, however might include unpatched safety points. Moreover, such plugins stay lively on consumer websites even when they’re faraway from the WordPress plugins repository.”
Most Fashionable Plugins With Vulnerabilities
As talked about earlier, severity scores vary from low, medium, excessive and significant. Patchstack compiled a listing of the most well-liked plugins with vulnerabilities.
In 2022 there have been 11 standard plugins with over one million lively installations that contained vulnerabilities. In 2023 Patchstack lowered the bar on installations from one million to over 100,000 installations. But regardless of making it simpler to get on the listing, there have been solely 9 standard plugins that had been discovered to have a vulnerability, far lower than in 2022.
In 2022 solely 5 out of 11 of the most well-liked plugins with vulnerabilities contained a excessive severity vulnerability, none contained a crucial degree vulnerability and the remaining had been medium degree severity.
These numbers turned considerably worse in 2023. Regardless of reducing the brink of what’s thought-about a preferred plugin, all 9 plugins on the listing contained crucial degree vulnerabilities, all of them. The overwhelming majority of the plugins on that listing, six out of 9, contained unauthenticated vulnerabilities, that means in that exploiting them is simple to scale with automation. The remaining three that required authentication solely required a subscriber degree entry, which is the best permission degree to accumulate, simply enroll, confirm the e-mail they usually’re in. That too may be scaled with automation.
Checklist Of Most Fashionable Plugins With Vulnerabilities
- Important Addons for Elementor 1M+ installations (severity score 9.8)
- WP Quickest Cache 1M+ installations (severity score 9.3)
- Gravity Varieties 940k installations (severity score 8.3)
- Fusion Builder 900k installations (severity score 8.5)
- Flatsome (Theme) 618k installations (severity score 8.3)

- Forminator 400k installations (severity score 9.8)
- WPvivid Backup and Migration 30ok installations (severity score 8.8)
- JetElements For Elementor 30ok installations (severity score 8.2)
State Of WordPress Safety Is Worse
When you really feel like there are extra vulnerabilities these days than ever earlier than, now you recognize the explanation, the statistics communicate for themselves. There are extra vulnerabilities in 2023 and a larger share are at excessive and significant ranges which may be exploited with automation at scale.
Which means that all publishers want to enhance their safety and ensure that somebody is taking accountability for auditing their plugins and themes regularly to ensure they’re all up to date and actively maintained.
SEOs ought to take discover as a result of safety rapidly turns into a rating drawback when Google drops a hacked web site from the search outcomes. Many SEOs who carry out web site audits don’t do even probably the most primary safety checks like verifying if the safety headers are in place, which is one thing that I do as part of each audit I carry out. At all times be certain that to have a dialogue with shoppers about their safety to ensure they’re conscious of the dangers.
Patchstack is an instance of a service that mechanically protects WordPress websites towards vulnerabilities even earlier than the plugin points a patch to repair the vulnerability. These sorts of providers are necessary with the intention to create a protection towards getting hacked and shedding search visibility and earnings.
