Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

Impact

An attacker can inject values into a PostgreSQL connection string by providing a parameter surrounded by single quotes.

Depending on how the library is used in the client software, this may allow an attacker to bypass the login process, gain access to the server's IP address, etc.

Patches

The vulnerability is fixed in ADOdb versions 5.20.21 (952de6c4273d9b1e91c2b838044f8c2111150c29) and 5.21.4 or later (b4d5ce70034c5aac3a1d51d317d93c037a0938d2).

The simplest patch is to delete line 29 in drivers/adodb-postgres64.inc.php:

diff --git a/drivers/adodb-postgres64.inc.php b/drivers/adodb-postgres64.inc.php
index d04b7f67..729d7141 100644

-   if (strncmp($s,"'",1) === 0 && substr($s,$len-1) == "'") return $s; // already quoted
 
    return "'".addslashes($s)."'";
 }

Workarounds

Ensure the parameters passed to ADOConnection::connect() or related functions (nConnect(), pConnect()) are not surrounded by single quotes.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for adodb/adodb-php. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update adodb/adodb-php to 5.20.21 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-65mj-7c86-79jf is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-65mj-7c86-79jf is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-65mj-7c86-79jf. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
