Deeper analysis
CVE-2026-2682 is a SQL injection vulnerability (CWE-74, CWE-89) in the Tsinghua Unigroup Electronic Archives System up to version 3.2.210802(62532). The issue affects an unknown function in the file /mine/PublicReport/prinReport.html?token=java, where manipulation of the comid argument enables SQL code injection.
The vulnerability is remotely exploitable over the network with low attack complexity and no user interaction required, but it demands low privileges (PR:L) from the attacker. Successful exploitation can result in limited impacts to confidentiality, integrity, and availability, as reflected in its CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).
Advisories from VulDB note the public disclosure of an exploit, including a proof-of-concept script on GitHub. The vendor was contacted early regarding the issue but provided no response, and no patches or official mitigations are available.
