Title

OpenClaw < 2026.2.2 - SSRF via Attachment Media URL Hydration

Summary

OpenClaw versions prior to 2026.2.2 contain a server-side request forgery vulnerability in attachment and media URL hydration that allows remote attackers to fetch arbitrary HTTP(S) URLs. Attackers who can influence media URLs through model-controlled sendAttachment or auto-reply mechanisms can trigger SSRF to internal resources and exfiltrate fetched response bytes as outbound attachments.

Vulnerability from osv_homebrew – Published: 2026-08-13 17:21 – Updated: 2026-11-13 09:11 – Source website

Summary

OpenClaw affected by SSRF via attachment/media URL hydration

Details

Summary

Versions of the openclaw npm package prior to 2026.2.2 could be coerced into fetching arbitrary http(s) URLs during attachment/media hydration. An attacker who can influence the media URL (for example via model-controlled sendAttachment or auto-reply media URLs) could trigger SSRF to internal resources and exfiltrate the fetched bytes as an outbound attachment.

Plain-English Explanation

OpenClaw can send files by downloading them first.

On vulnerable versions (< 2026.2.2), if an attacker could get OpenClaw to treat a URL as the “file to attach”, OpenClaw would download that URL from the gateway machine and then send the downloaded bytes back out as an attachment.

That matters because the gateway can often reach internal-only endpoints that an attacker cannot (for example 127.0.0.1 services, private RFC1918 addresses, or cloud metadata endpoints). This is a data-leak risk.

This does not directly grant code execution or shell access; it is about making the gateway perform HTTP requests and returning the response bytes.

2026.2.1 published 2026-02-02T11:45:27Z
2026.2.2 published 2026-02-04T00:56:41Z
This advisory was created 2026-02-05T10:42:26Z

Details

In affected versions, remote media fetching performed a raw fetch(url) without SSRF protections.

Starting in 2026.2.2, remote media fetching is guarded by SSRF checks (private/loopback/link-local blocking, DNS pinning, and redirect handling), so attempts to fetch 127.0.0.1, private RFC1918 space, or cloud metadata hostnames are rejected.

Proof of Concept

From any context where an attacker can influence an attachment/media URL, provide a media URL targeting an internal endpoint (example: http://127.0.0.1:9999/secret.txt).

On vulnerable versions (< 2026.2.2), the gateway fetches the URL and uses the response bytes as the attachment payload.

Fix

Mitigation

Upgrade to openclaw >= 2026.2.2.

  "details": "### Summary\n\nVersions of the `openclaw` npm package prior to `2026.2.2` could be coerced into fetching arbitrary `http(s)` URLs during attachment/media hydration. An attacker who can influence the media URL (for example via model-controlled `sendAttachment` or auto-reply media URLs) could trigger SSRF to internal resources and exfiltrate the fetched bytes as an outbound attachment.\n\n### Plain-English Explanation\n\nOpenClaw can send files by downloading them first.\n\nOn vulnerable versions (`\u003c 2026.2.2`), if an attacker could get OpenClaw to treat a URL as the \u201cfile to attach\u201d, OpenClaw would download that URL from the gateway machine and then send the downloaded bytes back out as an attachment.\n\nThat matters because the gateway can often reach internal-only endpoints that an attacker cannot (for example `127.0.0.1` services, private RFC1918 addresses, or cloud metadata endpoints). This is a data-leak risk.\n\nThis does not directly grant code execution or shell access; it is about making the gateway perform HTTP requests and returning the response bytes.\n\n### Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Affected: `\u003c 2026.2.2`\n- Fixed: `\u003e= 2026.2.2`\n\nRelease timeline (npm):\n\n- `2026.2.1` published `2026-02-02T11:45:27Z`\n- `2026.2.2` published `2026-02-04T00:56:41Z`\n- This advisory was created `2026-02-05T10:42:26Z`\n\n### Details\n\nIn affected versions, remote media fetching performed a raw `fetch(url)` without SSRF protections.\n\nStarting in `2026.2.2`, remote media fetching is guarded by SSRF checks (private/loopback/link-local blocking, DNS pinning, and redirect handling), so attempts to fetch `127.0.0.1`, private RFC1918 space, or cloud metadata hostnames are rejected.\n\n### Proof of Concept\n\nFrom any context where an attacker can influence an attachment/media URL, provide a media URL targeting an internal endpoint (example: `http://127.0.0.1:9999/secret.txt`).\n\nOn vulnerable versions (`\u003c 2026.2.2`), the gateway fetches the URL and uses the response bytes as the attachment payload.\n\n### Fix\n\nFix commits:\n\n- `81c68f582d4a9a20d9cca9f367d2da9edc5a65ae`\n- `9bd64c8a1f91dda602afc1d5246a2ff2be164647`\n\n### Mitigation\n\nUpgrade to `openclaw \u003e= 2026.2.2`.\n\nThanks @simecek for reporting.",

GHSA-WFP2-V9C7-FH79

Vulnerability from github – Published: 2026-02-17 21:30 – Updated: 2026-03-06 01:01

Summary

OpenClaw affected by SSRF via attachment/media URL hydration

Details

Summary

Plain-English Explanation

OpenClaw can send files by downloading them first.

This does not directly grant code execution or shell access; it is about making the gateway perform HTTP requests and returning the response bytes.

Affected Packages / Versions

Package: openclaw (npm)
Affected: < 2026.2.2
Fixed: >= 2026.2.2

Release timeline (npm):

2026.2.1 published 2026-02-02T11:45:27Z
2026.2.2 published 2026-02-04T00:56:41Z
This advisory was created 2026-02-05T10:42:26Z

Details

In affected versions, remote media fetching performed a raw fetch(url) without SSRF protections.

Proof of Concept

From any context where an attacker can influence an attachment/media URL, provide a media URL targeting an internal endpoint (example: http://127.0.0.1:9999/secret.txt).

On vulnerable versions (< 2026.2.2), the gateway fetches the URL and uses the response bytes as the attachment payload.

Fix

Fix commits:

9bd64c8a1f91dda602afc1d5246a2ff2be164647

Mitigation

Upgrade to openclaw >= 2026.2.2.

Thanks @simecek for reporting.

  "details": "### Summary\n\nVersions of the `openclaw` npm package prior to `2026.2.2` could be coerced into fetching arbitrary `http(s)` URLs during attachment/media hydration. An attacker who can influence the media URL (for example via model-controlled `sendAttachment` or auto-reply media URLs) could trigger SSRF to internal resources and exfiltrate the fetched bytes as an outbound attachment.\n\n### Plain-English Explanation\n\nOpenClaw can send files by downloading them first.\n\nOn vulnerable versions (`\u003c 2026.2.2`), if an attacker could get OpenClaw to treat a URL as the \u201cfile to attach\u201d, OpenClaw would download that URL from the gateway machine and then send the downloaded bytes back out as an attachment.\n\nThat matters because the gateway can often reach internal-only endpoints that an attacker cannot (for example `127.0.0.1` services, private RFC1918 addresses, or cloud metadata endpoints). This is a data-leak risk.\n\nThis does not directly grant code execution or shell access; it is about making the gateway perform HTTP requests and returning the response bytes.\n\n### Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Affected: `\u003c 2026.2.2`\n- Fixed: `\u003e= 2026.2.2`\n\nRelease timeline (npm):\n\n- `2026.2.1` published `2026-02-02T11:45:27Z`\n- `2026.2.2` published `2026-02-04T00:56:41Z`\n- This advisory was created `2026-02-05T10:42:26Z`\n\n### Details\n\nIn affected versions, remote media fetching performed a raw `fetch(url)` without SSRF protections.\n\nStarting in `2026.2.2`, remote media fetching is guarded by SSRF checks (private/loopback/link-local blocking, DNS pinning, and redirect handling), so attempts to fetch `127.0.0.1`, private RFC1918 space, or cloud metadata hostnames are rejected.\n\n### Proof of Concept\n\nFrom any context where an attacker can influence an attachment/media URL, provide a media URL targeting an internal endpoint (example: `http://127.0.0.1:9999/secret.txt`).\n\nOn vulnerable versions (`\u003c 2026.2.2`), the gateway fetches the URL and uses the response bytes as the attachment payload.\n\n### Fix\n\nFix commits:\n\n- `81c68f582d4a9a20d9cca9f367d2da9edc5a65ae`\n- `9bd64c8a1f91dda602afc1d5246a2ff2be164647`\n\n### Mitigation\n\nUpgrade to `openclaw \u003e= 2026.2.2`.\n\nThanks @simecek for reporting.",

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
