Title

OpenClaw < 2026.2.2 - Authorization Bypass via Unauthenticated Telegram Webhook

Summary

OpenClaw versions prior to 2026.2.2 fail to validate webhook secrets in Telegram webhook mode (must be enabled), allowing unauthenticated HTTP POST requests to the webhook endpoint that trust attacker-controlled JSON payloads. Remote attackers can forge Telegram updates by spoofing message.from.id and chat.id fields to bypass sender allowlists and execute privileged bot commands.

BREW-OPENCLAW-CLI-CVE-20… (GHSA-FHVM-J76F-QMJV)

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

Summary

OpenClaw has a potential access-group authorization bypass if channel type lookup fails

Details

Summary

When Telegram webhook mode is enabled without a configured webhook secret, OpenClaw may accept unauthenticated HTTP POST requests at the Telegram webhook endpoint and trust attacker-controlled update JSON. This can allow forged Telegram updates that spoof message.from.id / chat.id, potentially bypassing sender allowlists and executing privileged bot commands.

Affected Packages / Versions

Package: openclaw (npm)
Affected: <= 2026.1.30
Patched: >= 2026.2.1

Impact

An attacker who can reach the webhook endpoint can forge Telegram updates and impersonate allowlisted/paired senders by spoofing fields in the webhook payload (for example message.from.id). Impact depends on enabled commands/tools and the deployment’s network exposure.

Mitigations / Workarounds

Configure a strong channels.telegram.webhookSecret and ensure your reverse proxy forwards the X-Telegram-Bot-Api-Secret-Token header unchanged.

Fix Commit(s)

ca92597e1f9593236ad86810b66633144b69314d (config validation: webhookUrl requires webhookSecret)

Defense-in-depth / supporting fixes:

5643a934799dc523ec2ef18c007e1aa2c386b670 (default webhook listener bind host to loopback)
3cbcba10cf30c2ffb898f0d8c7dfb929f15f8930 (bound webhook request body size/time)
633fe8b9c17f02fcc68ecdb5ec212a5ace932f09 (runtime guard: reject webhook startup when secret is missing/empty)

Release Process Note

patched_versions is set to the first fixed release (2026.2.1).

Thanks @yueyueL for reporting.

GHSA-FHVM-J76F-QMJV

Vulnerability from github – Published: 2026-02-17 21:34 – Updated: 2026-03-06 00:58

Summary

OpenClaw has a potential access-group authorization bypass if channel type lookup fails

Details

Summary

Affected Packages / Versions

Package: openclaw (npm)
Affected: <= 2026.1.30
Patched: >= 2026.2.1

Impact

Mitigations / Workarounds

Configure a strong channels.telegram.webhookSecret and ensure your reverse proxy forwards the X-Telegram-Bot-Api-Secret-Token header unchanged.

Fix Commit(s)

ca92597e1f9593236ad86810b66633144b69314d (config validation: webhookUrl requires webhookSecret)

Defense-in-depth / supporting fixes:

5643a934799dc523ec2ef18c007e1aa2c386b670 (default webhook listener bind host to loopback)
3cbcba10cf30c2ffb898f0d8c7dfb929f15f8930 (bound webhook request body size/time)
633fe8b9c17f02fcc68ecdb5ec212a5ace932f09 (runtime guard: reject webhook startup when secret is missing/empty)

Release Process Note

patched_versions is set to the first fixed release (2026.2.1).

  "details": "## Summary\n\nWhen Telegram webhook mode is enabled without a configured webhook secret, OpenClaw may accept unauthenticated HTTP POST requests at the Telegram webhook endpoint and trust attacker-controlled update JSON. This can allow forged Telegram updates that spoof `message.from.id` / `chat.id`, potentially bypassing sender allowlists and executing privileged bot commands.\n\n## Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Affected: `\u003c= 2026.1.30`\n- Patched: `\u003e= 2026.2.1`\n\n## Impact\n\nAn attacker who can reach the webhook endpoint can forge Telegram updates and impersonate allowlisted/paired senders by spoofing fields in the webhook payload (for example `message.from.id`). Impact depends on enabled commands/tools and the deployment\u2019s network exposure.\n\n## Mitigations / Workarounds\n\n- Configure a strong `channels.telegram.webhookSecret` and ensure your reverse proxy forwards the `X-Telegram-Bot-Api-Secret-Token` header unchanged.\n\n## Fix Commit(s)\n\n- ca92597e1f9593236ad86810b66633144b69314d (config validation: `webhookUrl` requires `webhookSecret`)\n\nDefense-in-depth / supporting fixes:\n\n- 5643a934799dc523ec2ef18c007e1aa2c386b670 (default webhook listener bind host to loopback)\n- 3cbcba10cf30c2ffb898f0d8c7dfb929f15f8930 (bound webhook request body size/time)\n- 633fe8b9c17f02fcc68ecdb5ec212a5ace932f09 (runtime guard: reject webhook startup when secret is missing/empty)\n\n## Release Process Note\n\n`patched_versions` is set to the first fixed release (`2026.2.1`).\n\nThanks @yueyueL 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.
