CERT Polska coordinated disclosure of two SQL injection vulnerabilities affecting the Alior Bank 'raty' (installment payment) module for PrestaShop, used by commercial partners integrating Alior Bank financing options into their e-commerce backend. CVE-2026-7848 affects the hookActionObjectProductUpdateBefore, hookActionObjectCategoryUpdateBefore, and hookActionObjectCategoryAddAfter hook methods, where POST parameters (alior_product_promotion, alior_category_promotion, alior_category_enabled) are concatenated directly into SQL UPDATE statements without sanitization. CVE-2026-15600 affects the toggleCategoryPromotionAction method, where the POST parameter 'status' is similarly injected unsanitized into an UPDATE query.
Both vulnerabilities require an attacker to have access to the product or category add/edit functionality in the PrestaShop backoffice, meaning exploitation requires at least some authenticated access to the admin panel — this is not a pre-auth or unauthenticated remote attack. However, given backoffice access (e.g., a compromised low-privilege merchant employee account, or a malicious insider), an attacker could execute arbitrary SQL, potentially reading or modifying database contents including customer, order, and payment configuration data.
No evidence of in-the-wild exploitation is mentioned in the report; this was a responsibly disclosed finding by researcher Krzysztof Winiarski, coordinated through CERT Polska's CVD process. Fixes are available: CVE-2026-7848 is patched in module versions 9.0.7 and 8.1.11; CVE-2026-15600 is patched in versions 9.0.8 and 8.1.12. Defenders running PrestaShop stores with the Alior Bank raty module should upgrade immediately to the patched versions and audit backoffice account access controls and logs for anomalous product/category update requests containing SQL metacharacters in the named POST parameters.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,445 reports from 149 sources, 666 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
