# CVE-2025-65091: XWiki Full Calendar Macro vulnerable to SQL injection through Calendar.JSONService

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.3% , percentile 25: FIRST’s model estimates a 0.3% chance of exploitation activity in the next 30 days, higher than 25% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes org.xwiki.contrib:macro-fullcalendar-pom (Maven) <= 2.4.3, fixed in 2.4.5 . Check your lockfile, including transitive dependencies.

## What it is

XWiki Full Calendar Macro displays objects from the wiki on the calendar. Prior to version 2.4.5, users with the right to view the Calendar.JSONService page (including guest users) can exploit a SQL injection vulnerability by accessing database info or starting a DoS attack. This issue has been patched in version 2.4.5.

## Affected packages

- Maven `org.xwiki.contrib:macro-fullcalendar-pom` <= 2.4.3 → fixed: 2.4.5

## Affected products (CVE record)

- xwiki-contrib macro-fullcalendar: < 2.4.5

## Severity

- GitHub_M CVSS 3.1: 10 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 10.0 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.33% probability of exploitation activity in the next 30 days; percentile 25.
