CVE-2026-49213: TypeBot: SSRF protection bypass via IPv6 unspecified address in Typebot HTTP request execution

Noroxi assessment

Priority: Monitor (action score 32/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.40% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: baptisteArno typebot.io 3.17.2.

Low priority for now. Upgrade to baptisteArno typebot.io 3.17.2 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

TypeBot is a chatbot builder tool. Prior to 3.17.2, Typebot's shared SSRF validator in packages/lib/src/ssrf/validateHttpReqUrl.ts can be bypassed with the IPv6 unspecified address :: because validateIPAddress blocks local, metadata, and private ranges but does not block :: or its expanded form. A workspace editor or creator can configure a server-side HTTP Request block or guarded script fetch to make the Typebot server connect to local HTTP services through safeKy, including flows triggered by POST /v1/typebots/{publicId}/startChat or POST /v1/sessions/{sessionId}/continueChat. This issue is fixed in version 3.17.2.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.
