XWiki Platform may retrieve email addresses of all users

CVE-2023-34467 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

Impact

The mail obfuscation configuration was not fully taken into account and while the mail displayed to the end user was obfuscated:
- the rest response was also containing the mail unobfuscated
- user were able to filter and sort on the unobfuscated (allowing to infer the mail content)

The consequence was the possibility to retrieve the email addresses of all users even when obfuscated.

See https://jira.xwiki.org/browse/XWIKI-20333 for the reproduction steps.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
