CVE-2021-46702 (GCVE-0-2021-46702)
Vulnerability from cvelistv5 – Published: 2022-02-26 02:56 – Updated: 2024-08-04 05:17
VLAI?
Summary
Tor Browser 9.0.7 on Windows 10 build 10586 is vulnerable to information disclosure. This could allow local attackers to bypass the intended anonymity feature and obtain information regarding the onion services visited by a local user. This can be accomplished by analyzing RAM memory even several hours after the local user used the product. This occurs because the product doesn't properly free memory.
Severity ?
No CVSS data available.

CVE-2021-39246 (GCVE-0-2021-39246)
Vulnerability from cvelistv5 – Published: 2021-09-24 18:08 – Updated: 2024-08-04 02:06
VLAI?
Summary
Tor Browser through 10.5.6 and 11.x through 11.0a4 allows a correlation attack that can compromise the privacy of visits to v2 onion addresses. Exact timestamps of these onion-service visits are logged locally, and an attacker might be able to compare them to timestamp data collected by the destination server (or collected by a rogue site within the Tor network).
Severity ?
No CVSS data available.

CVE-2020-8516 (GCVE-0-2020-8516)
Vulnerability from cvelistv5 – Published: 2020-02-02 12:52 – Updated: 2024-08-04 10:03 Disputed
VLAI?
Summary
The daemon in Tor through 0.4.1.8 and 0.4.2.x through 0.4.2.6 does not verify that a rendezvous node is known before attempting to connect to it, which might make it easier for remote attackers to discover circuit information. NOTE: The network team of Tor claims this is an intended behavior and not a vulnerability
Severity ?
No CVSS data available.

VLAI?
Summary
Tor Browser through 8.5.3 has an information exposure vulnerability. It allows remote attackers to detect the browser's language via vectors involving an IFRAME element, because text in that language is included in the title attribute of a LINK element for a non-HTML page. This is related to a behavior of Firefox before 68.
