# CVE-2023-49599: WWBN AVideo Insufficient Entropy vulnerbaility

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 1.0% , percentile 61: FIRST’s model estimates a 1.0% chance of exploitation activity in the next 30 days, higher than 61% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes wwbn/avideo (Composer (PHP)) <= 12.4, no fixed version listed . Check your lockfile, including transitive dependencies.

## What it is

An insufficient entropy vulnerability exists in the salt generation functionality of WWBN AVideo dev master commit 15fed957fb. A specially crafted series of HTTP requests can lead to privilege escalation. An attacker can gather system information via HTTP requests and brute force the salt offline, leading to forging a legitimate password recovery code for the admin user.

## Affected packages

- Composer (PHP) `wwbn/avideo` <= 12.4 → fixed: none listed

## Affected products (CVE record)

- WWBN AVideo: dev master commit 15fed957fb

## Severity

- talos CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.96% probability of exploitation activity in the next 30 days; percentile 61.
