CVE-2024-2044: pgAdmin 4 vulnerable to Unsafe Deserialization and Remote Code Execution by an Authenticated user
pgAdmin
CVSS 9.4 Critical EPSS 79.5% · p99.6
Should you act?
High exploit likelihood
EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 79.5%, percentile 99.6: FIRST’s model estimates a 79.5% chance of exploitation activity in the next 30 days, higher than 99.6% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes
pgAdmin4(PyPI) < 8.4, fixed in 8.4. Check your lockfile, including transitive dependencies.
What it is
pgAdmin
From the GitHub advisory
pgAdmin prior to version 8.4 is affected by a path-traversal vulnerability while deserializing users’ sessions in the session handling code. If the server is running on Windows, an unauthenticated attacker can load and deserialize remote pickle objects and gain code execution. If the server is running on POSIX/Linux, an authenticated attacker can upload pickle objects, deserialize them and gain code execution.
Weakness type: CWE-31, CWE-22, CWE-502.

CVSS measures how bad a flaw is if exploited, not how likely exploitation is. Read it next to the exploitation data below.
Exploitation and urgency
- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc, automatable no, technical impact total.
- FIRST EPSS (model of 2026-10-21): 79.47% probability of exploitation activity in the next 30 days; percentile 99.6.
