CVE-2007-5795

Status: ModifiedMedium (6.3)—💥 Exploit

The hack-local-variables function in Emacs before 22.2, when enable-local-variables is set to :safe, does not properly search lists of unsafe or risky variables, which might allow user-assisted attackers to bypass intended restrictions and modify critical program variables via a file containing a Local variables declaration.

CVSS

Version: 2.0
Vector: AV:L/AC:M/Au:N/C:N/I:C/A:C
Base score: 6.3

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.72%
Percentile among all scored CVEs: 52
Score date: 10/7/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
