CVE-2025-8097 is a medium-severity vulnerability affecting the WoodMart WordPress theme developed by xTemos, specifically in all versions up to and including 8.2.6. The vulnerability arises from improper input validation (CWE-20) of the 'qty' parameter within the woodmart_update_cart_item function. This parameter controls the quantity of items added to the shopping cart. Due to insufficient validation, unauthenticated attackers can supply fractional quantities (e.g., 0.00001) which the system rounds in a way that reduces the cart total to zero dollars. This effectively allows attackers to bypass payment requirements and acquire virtual or downloadable products without paying. The vulnerability does not impact confidentiality or availability directly but compromises integrity by allowing unauthorized acquisition of products. The CVSS 3.1 base score is 5.3 (medium), reflecting that the attack vector is network-based, requires no privileges or user interaction, and impacts integrity but not confidentiality or availability. No known exploits are currently reported in the wild, and no official patches have been linked yet. The issue is rooted in the theme's failure to properly validate and sanitize input values for quantity, allowing manipulation of business logic in the e-commerce flow. This vulnerability is particularly relevant for e-commerce sites using the WoodMart theme to sell virtual or downloadable goods, where payment bypass can lead to direct financial losses and inventory mismanagement.

For European organizations operating e-commerce platforms using the WoodMart WordPress theme, this vulnerability poses a significant risk of financial loss and reputational damage. Attackers can exploit the flaw to obtain products without payment, leading to revenue loss and potential abuse of digital goods distribution. This can also disrupt inventory and sales analytics, complicating business operations. Since the vulnerability allows unauthenticated remote exploitation, it increases the attack surface, especially for publicly accessible online stores. Organizations may face increased fraud incidents, customer trust erosion, and potential regulatory scrutiny under European data protection and consumer protection laws if the vulnerability leads to broader security or transactional issues. The impact is more pronounced for businesses heavily reliant on virtual or downloadable products, such as digital media, software licenses, or online services, which are common in European digital markets.

European organizations should immediately audit their WordPress installations to identify if the WoodMart theme is in use and verify the version. Until an official patch is released, practical mitigations include implementing web application firewall (WAF) rules to detect and block requests with fractional or suspicious 'qty' parameter values. Input validation can be enforced at the server or application level by restricting 'qty' to positive integers only. Monitoring and alerting on abnormal cart activity or zero-dollar transactions can help detect exploitation attempts. Organizations should also consider disabling the affected cart update functionality temporarily if feasible. Regular backups and transaction logging will aid in forensic analysis if exploitation occurs. Once available, prompt application of official patches or theme updates from xTemos is critical. Additionally, educating development and security teams about this vulnerability will help ensure timely response and remediation.
