BOSH: Inadequate Encryption Strength
CVE-2026-41860 is a high-severity inadequate encryption strength vulnerability in BOSH from Cloud Foundry Foundation, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 282.1.9 as the first without the flaw, so updating BOSH to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.07% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update BOSH to 282.1.9 or a later version.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Cloud Foundry Foundation | BOSH | before 282.1.9 | 282.1.9 |

How the severity score breaks down
- Attack vector
- LocalThe attacker needs local access or must trick a user into running something.
- Attack complexity
- LowNo special conditions are needed; the attack works reliably.
- Privileges required
- LowA basic user account is enough.
- User interaction
- NoneNo action by a victim is required.
- Scope
- ChangedThe attack can reach beyond the vulnerable component into other systems.
- Confidentiality
- HighAll data handled by the component can be read.
- Integrity
- HighData or code can be modified at will.
- Availability
- HighThe component can be taken down completely.

Official description
CWE-326 in BOSH allows a local attacker to steal Basic-auth credentials or redirect UAA token requests via MITM. HttpRequestHelper#create_async_endpoint and #send_http_get_request_synchronous hard-code OpenSSL::SSL::VERIFY_NONE, enabling an attacker to intercept traffic between bosh-monitor and the BOSH director or UAA and steal credentials. Affected versions: - BOSH: all versions prior to v282.1.9 (inclusive); fixed in v282.1.9 or later

The underlying weakness: Inadequate Encryption Strength
The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
How developers prevent this class of flaw
- Use an encryption scheme that is currently considered to be strong by experts in the field.
