RARLAB WinRAR vulnerability
WinRAR contains a path traversal vulnerability (CWE-22) that allows attackers to execute arbitrary code with user privileges. The flaw has been exploited in the wild.
Verdict
Today item — known-exploited.
A path traversal flaw in WinRAR enables code execution in the user context. Active exploitation in the wild combined with low EPSS score suggests targeted rather than widespread attacks. Immediate patching is critical for affected systems.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Public proof-of-concept exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
20 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2025-12-09).
Probability (EPSS)
EPSS 0.81491 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: RARLAB, WinRAR. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-22 Path Traversal — weakness family: Path traversal / file.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious archive that exploits the path traversal to place executable code outside the intended extraction directory.
Business
User systems running WinRAR become compromised when processing untrusted archive files, risking data theft and lateral movement.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I deliver the weaponized archive via email or file-sharing platforms to target users.
Business
Organizational endpoints are exposed to remote code execution through routine file handling workflows.
3
Lateral reach — past segmentation narrative 3
Attacker
Upon extraction, my payload executes with the privileges of the user running WinRAR.
Business
Attackers gain persistent access to user accounts and can escalate to compromise network resources and sensitive data.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
