CVE-2026-85698— Turso through 0.8.0-pre.8 Out-of-Bounds Read Denial of Service

Quick assessment

Affected
tursodatabase turso
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Turso 在 0.8.0-pre.8 之前的版本中，其表叶页面读取器存在一个越界读取漏洞。该漏洞源于读取器使用攻击者可控的单元格计数（cell-count）字段，但未进行边界校验。攻击者可以通过构造一个恶意数据库文件，修改其中的单元格计数值，从而在查询时触发索引越界引发的 panic（程序崩溃）。任何打开不受信任数据库文件的应用程序都可能因此遭受服务拒绝（DoS）攻击。
