GHSA-489G-7RXV-6C8Q

Vulnerability from github – Published: 2026-07-10 18:01 – Updated: 2026-07-10 18:01
VLAI
Summary
MCP Atlassian: DNS-rebinding TOCTOU bypass of the SSRF fix (CVE-2026-27826)
Details

Summary

GHSA-7r34-79r5-rcc9's fix added validate_url_for_ssrf, which resolves the attacker-controlled X-Atlassian-{Jira,Confluence}-Url header host once at middleware time and trusts the result. But the outbound request is later built with the raw hostname and re-resolves at connect time with no IP pinning. An attacker-controlled rebinding DNS name returns a public IP on the guard's lookup (validation passes) and 169.254.169.254 / an internal IP on the request's lookup (the socket connects there) → unauthenticated SSRF to cloud metadata / internal services on the patched build.

Relationship to CVE-2026-27826 / GHSA-7r34-79r5-rcc9 (incomplete fix — please read first)

This is an incomplete-fix sibling of the published GHSA-7r34-79r5-rcc9 (the X-Atlassian-*-Url header SSRF). That fix (PR #986/#1005) added a single middleware-time resolve + allowlist DNS-skip, but does not pin the validated IP to the connection — the fetcher re-resolves the raw hostname at connect time, so the documented SSRF mitigation is incomplete against DNS-rebinding. The other advisory GHSA-xjgw-4wvw-rgm4 (file-write) is unrelated. Verified live (2026-06-27): neither advisory, nor any open PR/issue (rebind/TOCTOU/getaddrinfo/pin → 0), covers connect-time re-resolution. Filing as an incomplete-fix of GHSA-7r34 (not a standalone fresh SSRF).

Affected

src/mcp_atlassian/utils/urls.py + servers/main.py + servers/dependencies.py, HEAD ba72540 (PyPI mcp-atlassian, patched ≥0.17.0). CWE-918 (SSRF) via CWE-367 (TOCTOU).

Vulnerable code

utils/urls.py validate_url_for_ssrf (≈184-205) resolves + validates, then returns a string verdict, not a pinned IP:

def validate_url_for_ssrf(url: str) -> str | None:   # returns an error string or None — NO IP is pinned
    ...
    # resolves the host, checks each resolved IP is global, then DISCARDS the IP

servers/main.py:526,534 calls it once in middleware. servers/dependencies.py:544-561 then builds the fetcher with url = <raw header hostname> (no pinned IP, no custom resolver / cached-getaddrinfo adapter), so the actual request re-resolves the name.

PoC (executed — boundary demonstration)

The PoC loads the real urls.py by path (importlib, sha256 printed) and drives the genuine validate_url_for_ssrf, simulating the two resolutions via getaddrinfo:

[CHECK ] validate_url_for_ssrf('http://rebind.attacker.example') -> None        (getaddrinfo#1 = 93.184.216.34 global -> guard PASSED)
[CONNECT] getaddrinfo call #2 returned 169.254.169.254 -> the socket connects HERE
[PROOF ] guard validated IP 93.184.216.34 but connection targets 169.254.169.254  => SSRF on the PATCHED build
[CONTROL] if guard SAW 169.254.169.254 at check time -> blocks it correctly
[PIN   ] validate_url_for_ssrf returns a verdict (None), NOT an IP; dependencies.py builds url=raw hostname -> NO pin
ALL PoC ASSERTIONS PASSED — DNS-rebind TOCTOU bypass demonstrated.

Honest scope of the PoC: this is a boundary demonstration — it proves the structural TOCTOU (the guard validates an IP it then discards; the connection re-resolves an unpinned hostname). It does not demonstrate a live end-to-end SSRF on a running server; that additionally requires an attacker-controlled fast-rebinding authoritative DNS responder winning the resolve→connect window. Flagging this explicitly rather than overclaiming.

Impact

Same as parent GHSA-7r34 (unauth read of cloud-metadata IAM creds / internal-service reach), reachable again on the patched version. The X-Atlassian-*-Url headers are processed in UserTokenMiddleware before fetcher creation, so an unauthenticated/low-priv caller controls the host.

Severity

High — CVSS v3.1 AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N ≈ 7.x, aligned to the parent (8.2) with AC:H for the rebinding-race precondition. Honest caveat (above): the executed PoC proves the missing IP-pin structurally; a live exploit additionally needs an attacker rebinding-DNS. Not Critical.

Remediation

Pin the connection to the IP that validate_url_for_ssrf validated: use a custom resolver / cached-getaddrinfo requests-adapter (or pass the validated IP with a Host header), so the connect cannot re-resolve to a different address.

Dedup / freshness (re-verified live 2026-06-27)

Advisories GHSA-7r34-79r5-rcc9 (original header SSRF this bypasses) + GHSA-xjgw-4wvw-rgm4 (file-write, unrelated). Neither covers connect-time re-resolution / rebinding. PR #986/#1005 (the fix) add a single middleware-time resolve + allowlist DNS-skip, no pinning. gh search prs/issues for rebind/TOCTOU/getaddrinfo/pin → 0. First-party code. Fresh at HEAD ba72540.

But the outbound request is later built with the **raw hostname** and **re-resolves at connect time with no IP pinning**. An attacker-controlled rebinding DNS name returns a public IP on the guard\u0027s lookup (validation passes) and `169.254.169.254` / an internal IP on the request\u0027s lookup (the socket connects there) \u2192 unauthenticated SSRF to cloud metadata / internal services on the **patched** build.\n\n### Relationship to CVE-2026-27826 / GHSA-7r34-79r5-rcc9 (incomplete fix \u2014 please read first)\nThis is an **incomplete-fix sibling** of the published `GHSA-7r34-79r5-rcc9` (the `X-Atlassian-*-Url` header SSRF). That fix (PR #986/#1005) added a single middleware-time resolve + allowlist DNS-skip, but **does not pin the validated IP to the connection** \u2014 the fetcher re-resolves the raw hostname at connect time, so the documented SSRF mitigation is incomplete against DNS-rebinding. The other advisory `GHSA-xjgw-4wvw-rgm4` (file-write) is unrelated. Verified live (2026-06-27): neither advisory, nor any open PR/issue (`rebind`/`TOCTOU`/`getaddrinfo`/`pin` \u2192 0), covers connect-time re-resolution. Filing as an incomplete-fix of GHSA-7r34 (not a standalone fresh SSRF).\n\n### Affected\n`src/mcp_atlassian/utils/urls.py` + `servers/main.py` + `servers/dependencies.py`, HEAD `ba72540` (PyPI `mcp-atlassian`, patched \u22650.17.0). **CWE-918** (SSRF) via **CWE-367** (TOCTOU).\n\n### Vulnerable code\n`utils/urls.py` `validate_url_for_ssrf` (\u2248184-205) resolves + validates, then returns a **string verdict, not a pinned IP**:\n```python\ndef validate_url_for_ssrf(url: str) -\u003e str | None:   # returns an error string or None \u2014 NO IP is pinned\n    ...\n    # resolves the host, checks each resolved IP is global, then DISCARDS the IP\n```\n`servers/main.py:526,534` calls it once in middleware. `servers/dependencies.py:544-561` then builds the fetcher with `url = \u003craw header hostname\u003e` (no pinned IP, no custom resolver / cached-getaddrinfo adapter), so the actual request re-resolves the name.\n\n### PoC (executed \u2014 boundary demonstration)\nThe PoC loads the **real** `urls.py` by path (`importlib`, `sha256` printed) and drives the genuine `validate_url_for_ssrf`, simulating the two resolutions via `getaddrinfo`:\n```\n[CHECK ] validate_url_for_ssrf(\u0027http://rebind.attacker.example\u0027) -\u003e None        (getaddrinfo#1 = 93.184.216.34 global -\u003e guard PASSED)\n[CONNECT] getaddrinfo call #2 returned 169.254.169.254 -\u003e the socket connects HERE\n[PROOF ] guard validated IP 93.184.216.34 but connection targets 169.254.169.254  =\u003e SSRF on the PATCHED build\n[CONTROL] if guard SAW 169.254.169.254 at check time -\u003e blocks it correctly\n[PIN   ] validate_url_for_ssrf returns a verdict (None), NOT an IP; dependencies.py builds url=raw hostname -\u003e NO pin\nALL PoC ASSERTIONS PASSED \u2014 DNS-rebind TOCTOU bypass demonstrated.\n```\n**Honest scope of the PoC:** this is a **boundary** demonstration \u2014 it proves the structural TOCTOU (the guard validates an IP it then discards; the connection re-resolves an unpinned hostname). It does **not** demonstrate a live end-to-end SSRF on a running server; that additionally requires an attacker-controlled fast-rebinding authoritative DNS responder winning the resolve\u2192connect window. Flagging this explicitly rather than overclaiming.\n\n### Impact\nSame as parent GHSA-7r34 (unauth read of cloud-metadata IAM creds / internal-service reach), reachable again on the patched version. The `X-Atlassian-*-Url` headers are processed in `UserTokenMiddleware` before fetcher creation, so an unauthenticated/low-priv caller controls the host.\n\n### Severity\n**High \u2014 CVSS v3.1 `AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N` \u2248 7.x**, aligned to the parent (8.2) with `AC:H` for the rebinding-race precondition. Honest caveat (above): the executed PoC proves the missing IP-pin structurally; a live exploit additionally needs an attacker rebinding-DNS. Not Critical.\n\n### Remediation\nPin the connection to the IP that `validate_url_for_ssrf` validated: use a custom resolver / cached-`getaddrinfo` `requests`-adapter (or pass the validated IP with a `Host` header), so the connect cannot re-resolve to a different address.\n\n### Dedup / freshness (re-verified live 2026-06-27)\nAdvisories `GHSA-7r34-79r5-rcc9` (original header SSRF this bypasses) + `GHSA-xjgw-4wvw-rgm4` (file-write, unrelated). Neither covers connect-time re-resolution / rebinding.

CAPEC-664: Server Side Request Forgery

An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
