In the first quarter of 2026, WooCommerce store owners dealt with eight confirmed SQL injection vulnerabilities. Most of these were found in plugins and extensions, not in WooCommerce itself.

Some of the most serious issues did not require attackers to log in, which made it easier for them to target sites. At the time of review, two plugins still did not have fixes. Store owners should disable risky plugins, limit who can access them, watch activity logs, update security settings, and check their databases until updates are available.

SQL injection is still one of the biggest threats for online stores because it can reveal customer information, order details, admin data, and other sensitive records in the website’s database. Even if the issue is in an add-on and not WooCommerce itself, it can still have a serious impact on the store.

The eight issues found in Q1 2026 fall into two groups: those that do not need a login and those that do. The first group is especially concerning because attackers do not need stolen passwords or special access. If a weak spot is open, the store is much easier to attack.

The group that needs a login might seem less urgent, but these issues are still serious. If a flaw requires Shop Manager, Subscriber, or Administrator access, attackers can still take advantage if they get into lower-level accounts, use weak passwords, or combine several problems.

The most serious issues from Q1 2026 were in this group.

CVE-2026-0702 — VidShop – Shoppable Videos for WooCommerce affected versions up to 1.1.4 through the fields parameter. It was rated 7.5 High and patched in version 1.1.5.

CVE-2026-2232 — Product Table and List Builder for WooCommerce Lite affected versions up to 4.6.2 through the search parameter. It was also rated 7.5 High and patched in 4.6.3.

CVE-2026-24993 — Advanced Reporting & Statistics for WooCommerce – Orders, Products & Customers Reporting affected versions up to 4.1.3. This issue also received a 7.5 High rating and was patched in 4.1.4.

CVE-2026-2579 — WowStore – Store Builder & Product Blocks for WooCommerce affected versions up to 4.4.3 via the search parameter. It carried a 7.5 High rating and was fixed in 4.4.4.

CVE-2026-31920 — Product Rearrange for WooCommerce affected versions up to 1.2.2. It was described as a blind SQL injection issue, and at the time of review, no known patch was available.

This group clearly shows a risk. The problem is not just that these issues exist, but that they are easy to access. If attackers can exploit weak spots without logging in, they can move quickly from finding the problem to using it. For store owners, waiting to fix these issues is much riskier than it appears.

The second group included issues that required someone to be logged in, but these should not be overlooked.

CVE-2026-0678 — Shipping Rates by City for WooCommerce affected versions up to 1.0.3 through the cities parameter. Exploitation required Shop Manager access or higher. It was rated 4.9 Medium, and no known patch was listed at the time of review.

CVE-2026-1370 — SIBS - WooCommerce affected versions up to 2.2.0 via the referencedId parameter. This issue required Administrator access or higher and was rated 4.9 Medium.

CVE-2026-22335 — WooCommerce Frontend Manager – Ultimate affected versions below 6.7.7. It required Subscriber-level access or above, was rated 6.5 Medium, and was patched in version 6.7.7.

These issues show that relying only on user roles is not enough. Many online stores have different users, such as support staff, shop managers, marketers, and temporary workers. If a plugin needs a login, any account with the right access could be used to reach the database.

When looking at all eight issues, three main patterns stand out.

First, most of the risk comes from plugins that add features to WooCommerce, not from WooCommerce itself. In this review, no SQL injection issues were found in WooCommerce in 2026. All confirmed problems were in plugins and add-ons that store owners use for extra features. This shows that using third-party tools can make your site more vulnerable.

Second, the problems are much more serious when no login is needed. The most dangerous issues this quarter were those that did not require a login, like those in VidShop, Product Table, List Builder, Advanced Reporting, WowStore, and Product Rearrange. These issues make it much easier for attackers to access the database or launch attacks without knowing exactly what they will find.

Third, sometimes it is not clear if a fix is available. Two important cases had no known fix at the time: Product Rearrange for WooCommerce and Shipping Rates by City for WooCommerce. If you use these, you may need to turn off the add-on, limit access, add extra security tools, watch logs more closely, and check the database for anything unusual.

For WooCommerce businesses, this quarter’s findings show that security problems often come from plugins, not WooCommerce itself. Keeping all your plugins up to date is very important for protecting your store.

Review every WooCommerce add-on on your site, especially those used for reports, layout, search, shipping, or admin tasks. In your WordPress dashboard, check the plugin versions and compare them to the ones listed above. Treat any outdated or unsupported plugin as a risk until you know it is safe.

Pay close attention to plugins that people use directly on your website and that handle user data. Focus on product search, reports, forms, reviews, advanced filters, and any tools that work with store data. If a plugin accepts user input, treat it as a higher risk for SQL injection.

It is also wise to limit how many people have special roles in your store. The login-required issues from Q1 2026 show that even accounts with lower or mid-level access can matter. Limit what users can do, remove unused accounts, require strong passwords, and set up extra checks for admin and manager roles. Also, remember that fixing a problem does not make your store safe until you install the update. For busy stores, waiting to update can leave you open to attacks even after a fix is available. To reduce this risk, turn on automatic updates for plugins and WordPress if possible, or set a regular schedule to update everything. Automatic or scheduled updates help make sure security fixes are applied quickly, so your store is not left open to known problems.

The SQL injection vulnerabilities found in WooCommerce in Q1 2026 are a strong reminder that online store security involves more than just WooCommerce. Plugins, add-ons, reporting tools, and store management tools can all create serious database risks if they are not fixed, monitored, or replaced quickly. For online sellers, the safest approach is to apply fixes right away, choose plugins carefully, stay alert, and check security often.
