CVE-2026-94534
lamp-cloud through 5.10.0 fails to validate user identity in PUT /anyone/baseInfo and PUT /anyone/avatar endpoints, allowing authenticated attackers to modify arbitrary user profiles. Attackers can supply target user IDs in request bodies to rewrite profile fields including nickname, ID card, sex, nation, education, work description, and avatar attachments of other users.
What this means for your business
- An attacker can use it remotely, over a network, with an ordinary user login, and without anyone at your company clicking anything.
What to do
- 1Ask your IT team or provider whether any of your systems use the affected product.
- 2If you do, follow the vendor's guidance. No patch reference has been published yet.
