Quick assessment

Affected

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.

Papermerge Core 3.5.3 及更早版本存在一个缺失授权检查的安全漏洞。该漏洞允许经过身份验证的用户通过提供 参数，列出其他用户组的标签和文档类型。攻击者若已知某个用户组的 UUID，可通过调用 GET /tags/all 或 GET /document-types/all 接口来获取不属于该用户组的元数据。这些接口未对用户所属关系进行校验（即跳过了 user_belongs_to 检查），从而导致敏感信息泄露。

Papermerge Core through 3.5.3 contains a missing authorization vulnerability that allows authenticated users to list other groups' tags and document types by supplying a group_id parameter. Attackers who know a group's UUID can query GET /tags/all or GET /document-types/all, which skip the user_belongs_to check, to disclose metadata of groups they do not belong to.
