Deeper analysis
CVE-2026-3287 is a SQL injection vulnerability in youlaitech youlai-mall version 2.0.0, affecting the listPagedSpuForApp function within the App-side Product Pagination Endpoint. The flaw resides in the file mall-pms/pms-boot/src/main/java/com/youlai/mall/pms/controller/app/SpuController.java, where manipulation of the sortField or sort arguments enables injection. It is classified under CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection), with a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).
The vulnerability allows remote exploitation by low-privileged authenticated users over the network with low attack complexity and no user interaction required. Attackers can achieve limited impacts on confidentiality, integrity, and availability, potentially enabling unauthorized data access, modification, or disruption via injected SQL payloads.
Advisories from VulDB indicate no vendor response or patch availability despite early notification; the exploit code has been publicly released, increasing the risk of active attacks. References include VulDB entries (ctiid.348016, id.348016, submit.758977) and a Feishu document for further details.

Why these techniques?
SQL injection in exposed web app endpoint (SpuController listPagedSpuForApp) directly enables T1190 (Exploit Public-Facing Application) for initial or post-auth access; injected payloads allow unauthorized retrieval/modification of database contents, mapping to T1213.006 (Data from Information Repositories: Databases).

Directly requires validation and neutralization of untrusted inputs (sortField/sort) before they reach SQL statements in listPagedSpuForApp.
Limits the database privileges granted to the application account so that even a successful injection yields only minimal impact on confidentiality/integrity/availability.
Enables monitoring and anomaly detection on database queries or application logs to identify attempted or successful SQL injection payloads against the pagination endpoint.
