Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: DiscordNotifications (by Miraheze) has a code flaw allowing requests to **arbitrary URLs** via `curl` and `file_get_contents`.โฆ
๐ก๏ธ **Root Cause**: **CWE-400** (Uncontrolled Resource Consumption). The flaw lies in sending HTTP requests to **unvalidated/any URL**. This lack of restriction leads to resource exhaustion or SSRF attacks.โฆ
๐ฅ **Affected**: **Miraheze**'s open-source app **DiscordNotifications**. ๐ฆ **Component**: The notification module handling external URL requests. โ ๏ธ Check if you are running this specific Miraheze integration.
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Capabilities**: Can trigger **DoS** (crashing services) and perform **SSRF** (probing internal networks).โฆ
๐งช **Public Exploit?**: **No PoC** listed in data. ๐ **References**: GitHub Security Advisory (GHSA-gvfx-p3h5-qf65) and Commit Fix are available. Wild exploitation is currently **low** due to lack of public PoC.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for instances of `curl` or `file_get_contents` in **DiscordNotifications** code. ๐ Look for **unvalidated URL inputs**.โฆ
โ **Fixed?**: **YES**. Official patch available via GitHub commit `1f20d850...`. ๐ **Action**: Update to the latest version or apply the specific commit fix provided by Miraheze. Check GHSA advisory for details.
Q9What if no patch? (Workaround)
๐ง **No Patch?**: **Mitigation**: Implement **URL allowlisting** or **validation** before passing to `curl`/`file_get_contents`. ๐ Block internal/private IP ranges. Restrict outbound HTTP requests to trusted domains only.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **HIGH**. Despite low data leak risk, **Availability Impact is High (A:H)**. DoS and SSRF are critical for operational stability. ๐ **Priority**: Patch immediately to prevent service disruption.
