{"id":"CVE-2026-112285","kind":"vulnerability","aliases":["CVE-2026-112285"],"related":[],"title":"Thelia: coupon usage limits bypassed through pay-later and cancelled orders","description":"Thelia before 3.1.5 and 3.2.x before 3.2.4 contains a business logic vulnerability that allows authenticated customers to bypass coupon usage limits because usage is counted only when orders become paid. Attackers can place multiple pay-later orders while a usage remains, or cancel paid orders to inflate max_usage, gaining unlimited discounts.","summary":"Thelia, an open-source e-commerce platform, counts coupon usage only when orders are paid, so a logged-in customer can place several pay-later orders while one use remains. Cancelling paid orders also raises the coupon's max_usage, letting the customer keep getting unlimited discounts.","severity":"medium","cvss":5.3,"epss":null,"exploited":false,"exploited_at":null,"products":[],"ecosystems":[],"tags":["e-commerce","php","runtime","self-hosted","thelia"],"not_affected_if":["no-usage-limited-coupons","patched-version"],"how_to_check":"- Check the installed Thelia version in the project's composer.json or the admin footer; versions below `3.1.5` or `3.2.x` below `3.2.4` are affected.\n- Review coupons with a usage limit for unusual order counts from single customers.","fix":"- Upgrade Thelia to `3.1.5` or later on the 3.1 line, or to `3.2.4` or later on the 3.2 line.","status":"open","published_at":"2026-10-19T14:17:06+00:00","first_seen_at":"2026-10-23T21:57:18+00:00","triaged_at":"2026-10-25T04:25:09+00:00","updated_at":"2026-10-25T04:25:09+00:00","category":"runtime","confidence":0.6,"triage":{"at":"2026-10-25T04:25:09Z","model":"claude-haiku-5-5","output":{"fix":"- Upgrade Thelia to `3.1.5` or later on the 3.1 line, or to `3.2.4` or later on the 3.2 line.","reach":"internet","title":"Thelia: coupon usage limits bypassed through pay-later and cancelled orders","impact":"low","summary":"Thelia, an open-source e-commerce platform, counts coupon usage only when orders are paid, so a logged-in customer can place several pay-later orders while one use remains.
