CVE-2023-34467 is a high-severity (CVSS 7.5) CWE-402 vulnerability in org.xwiki.platform:xwiki-platform-livetable-ui. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2023-34467 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
XWiki Platform is a generic wiki platform. Starting in version 3.5-milestone-1 and prior to versions 14.4.8, 14.10.4, and 15.0-rc-1, the mail obfuscation configuration was not fully taken into account. While the mail displayed to the end user was obfuscated, the rest response was also containing the mail unobfuscated and users were able to filter and sort on the unobfuscated, allowing them to infer the mail content. The consequence was the possibility to retrieve the email addresses of all users even when obfuscated. This has been patched in XWiki 14.4.8, 14.10.4, and 15.0-rc-1.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-livetable-ui. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update org.xwiki.platform:xwiki-platform-livetable-ui to 14.4.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-34467 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2023-34467 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2023-34467. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
