GHSA-FPMH-VX4H-XC33
Vulnerability from github – Published: 2026-08-14 19:25 – Updated: 2026-08-14 19:25Summary
Description
An Insecure Default Initialization of Resource (CWE-1188) issue in the OpenAM default configuration ships the iPlanetDirectoryPro SSO cookie with HttpOnly=false. Also, the iPlanetDirectoryPro SSO cookie is used as a CSRF token in OAuth/OIDC flows. This affects OpenAM Community Edition through version 16.0.6 and was patched in version 16.1.1.
Impact
A single click on an attacker link may yield full SSO session theft of any authenticated console user when chained with any other same-origin XSS in the OpenAM origin. The missing SameSite default also widens the CSRF surface. Also, because the consent flow reuses the SSO cookie as its CSRF token, any XSS in the OpenAM origin both steals the session and completes attacker-driven OAuth consent grants in one step.
Patch
This has been patched in OpenAM Community Edition version 16.1.1. Users are encouraged to update to the latest release.

GHSA-GRH8-3P95-F9RR
Vulnerability from github – Published: 2026-09-15 20:00 – Updated: 2026-09-15 20:00The CookieJar client middleware decides whether to attach a cookie to an outgoing request using an unanchored substring test on the host and path, instead of the domain match specified by RFC6265 5.1.3. A cookie stored for example.com is therefore sent to any host whose name merely contains example.com (e.g. evilexample.com), leaking potentially sensitive cookies to an attacker-chosen host.
Impact
Disclosure of session and authentication cookies to an attacker-controlled host, enabling session hijack of the application's outbound calls.
Preconditions
- Application uses the
CookieJarclient middleware. - Application can be induced to make an outbound request to a host controlled by the attacker, where the hostname contains the targeted domain as a substring.
Workarounds
- Do not use the
CookieJarwith clients that fetch attacker-influenced URLs - Apply a separate
CookieJarper trusted origin.

GHSA-M452-Q8C9-RG2F
Vulnerability from github – Published: 2026-08-26 14:35 – Updated: 2026-08-26 14:35Impact
A cookie tossing / cookie injection issue (CWE-1275). ThreadSafeCookieStore stored a cookie under the value of its Domain attribute without verifying that the responding host is allowed to set a cookie for that domain (RFC 6265 §5.3 step 6). A host the client connects to can therefore plant a cookie scoped to an unrelated domain, and the client will then send that cookie on later requests to that domain.
Who is Impacted
Applications that use a single AsyncHttpClient instance - and thus the default, shared CookieStore - to reach both an attacker-influenced host and a trusted host. Typical exposure: crawlers, link-preview / webhook fetchers, SSRF-style "fetch this URL" features, multi-backend aggregators, or following redirects to an attacker-controlled host. The attacker can write a cookie the client presents to the victim host (session fixation, overwriting a session id / CSRF-token cookie); they cannot read the victim host's cookies. Applications that talk only to a fixed trusted backend, or that disable/scope the cookie store, are not exposed.
Patches
Fixed in 3.0.11 and 2.16.0
Workarounds
- Disable the cookie store (setCookieStore(null)) when cookies are not needed; or
- Use a separate AsyncHttpClient (separate cookie store) per trust domain so an attacker-influenced host and a trusted host never share a jar
- Supply a custom CookieStore whose add(Uri, Cookie) rejects cookies whose Domain is not domain-matched by the request host.

GHSA-PHG3-3G28-WQ9V
Vulnerability from github – Published: 2026-09-21 15:47 – Updated: 2026-09-21 15:47Summary
Hatchet version v0.86.26 and below is vulnerable to OAuth state CSRF (login CSRF / account fixation).
The vulnerable code clears the session oauth_state_<integration> value to the empty string "" after a successful OAuth callback rather than removing the key, and the subsequent state-equality check then accepts an empty ?state= parameter on any later callback request — allowing an unauthenticated attacker to bind an already-authenticated victim's session cookie to an attacker-controlled OAuth identity (account takeover via login-CSRF).
Impact
Affected configurations: any deployment that has enabled at least one of auth.google.enabled, auth.github.enabled, or the Slack integration, and where the victim has completed at least one OAuth flow on that integration in the current session. Bug present on main HEAD and in every tagged release up to and including v0.86.26 (commit 243f41d9e1161e70d47dfc0a6509f1c4ddfc9c23).

Mitigation
Set the SameSite attribute of a sensitive cookie to 'Lax' or 'Strict'. This instructs the browser to apply this cookie only to same-domain requests, which provides a good Defense in Depth against CSRF attacks. When the 'Lax' value is in use, cookies are also sent for top-level cross-domain navigation via HTTP GET, HEAD, OPTIONS, and TRACE methods, but not for other HTTP methods that are more like to cause side-effects of state mutation.
CAPEC-62: Cross Site Request Forgery
An attacker crafts malicious web links and distributes them (via web pages, email, etc.), typically in a targeted manner, hoping to induce users to click on the link and execute the malicious action against some third-party application. If successful, the action embedded in the malicious link will be processed and accepted by the targeted application with the users' privilege level. This type of attack leverages the persistence and implicit trust placed in user session cookies by many web applications today. In such an architecture, once the user authenticates to an application and a session cookie is created on the user's system, all following transactions for that session are authenticated using that cookie including potential actions initiated by an attacker and simply "riding" the existing session cookie.
