Joe talks about how helping the helpers can put a fire in you and the importance of keeping nonprofits cybersecure.
### Summary PKCE was implemented in the OAuth implementation in workers-oauth-provider that is part of[ MCP framework](https://github.com/cloudflare/workers-mcp). However, it was found that an attacker could cause the check to be skipped. ### Impact PKCE is a defense-in-depth mechanism against certain kinds of attacks and was an optional extension in OAuth 2.0 which became required in the OAuth 2.1 draft. (Note that the MCP specification requires OAuth 2.1.) This bug completely bypasses PKCE protection. ### Patches Fixed in: https://github.com/cloudflare/workers-oauth-provider/pull/27 We patched up the vulnerabilities in the latest version, v 0.0.5 of the Workers OAuth provider (https://www.npmjs.com/package/@cloudflare/workers-oauth-provider). You'll need to update your MCP servers to use that version to resolve the vulnerability. ### Workarounds None
### Summary PKCE was implemented in the OAuth implementation in workers-oauth-provider that is part of[ MCP framework](https://github.com/cloudflare/workers-mcp). However, it was found that an attacker could cause the check to be skipped. ### Impact Under certain circumstances (see below), if a victim had previously authorized with a server built on workers-oath-provider, and an attacker could later trick the victim into visiting a malicious web site, then attacker could potentially steal the victim's credentials to the same OAuth server and subsequently impersonate them. In order for the attack to be possible, the OAuth server's authorized callback must be designed to auto-approve authorizations that appear to come from an OAuth client that the victim has authorized previously. The authorization flow is not implemented by workers-oauth-provider; it is up to the application built on top to decide whether to implement such automatic re-authorization. However, many applications do impl...
Improper escaping of a query parameter may allow an attacker to execute arbitrary SQL statements when the code using ADOdb connects to a PostgreSQL database and calls pg_insert_id() with user-supplied data. Note that the indicated Severity corresponds to a worst-case usage scenario. ### Impact PostgreSQL drivers (postgres64, postgres7, postgres8, postgres9). ### Patches Vulnerability is fixed in ADOdb 5.22.9 (11107d6d6e5160b62e05dff8a3a2678cf0e3a426). ### Workarounds Only pass controlled data to pg_insert_id() method's $fieldname parameter, or escape it with pg_escape_identifier() first. ### Credits Thanks to Marco Nappi (@mrcnpp) for reporting this vulnerability.
