Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Apr 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 30 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade dde-control-center to 6.1.80 or 5.9.9; linuxdeepin/dde-control-center to 6.1.80.

AI-suggested

The vulnerability is fixed in dde-control-center versions 6.1.80 and 5.9.9. Users and administrators should upgrade affected dde-control-center installations to at least these versions to remediate the issue. Patch status is not explicitly stated as 'patchAvailable' in the data, but the vendor has fixed the issue in these versions, so updating to these or later versions is the recommended mitigation.

Description

dde-control-center is the control panel of DDE, the Deepin Desktop Environment.plugin-deepinid is a plugin in dde-control-center, which provides the deepinid cloud service. Prior to 6.1.80, plugin-deepinid is configured to skip TLS certificate verification when fetching the user's avatar from openapi.deepin.com or other providers. An MITM attacker could intercept the traffic, replace the avatar with a malicious or misleading image, and potentially identify the user by the avatar. This vulnerability is fixed in dde-control-center 6.1.80 and 5.9.9.

Impact

An attacker capable of performing a man-in-the-middle attack can intercept and alter avatar images fetched by the vulnerable plugin, potentially misleading users or enabling identification of users by their avatars. The confidentiality and integrity of the avatar data are impacted, but there is no direct impact on system availability or broader system compromise indicated.

Summary

The dde-control-center's plugin-deepinid in linuxdeepin versions prior to 6.1.80 and 5.9.9 does not properly validate TLS certificates when retrieving user avatars from specified cloud services. This improper certificate validation (CWE-295) can be exploited by an attacker positioned to intercept network traffic (MITM) to substitute the avatar image. The vulnerability has a CVSS 3.1 base score of 5.4, indicating medium severity, with impacts on confidentiality and integrity but no availability impact. The vulnerability is addressed by updates to dde-control-center 6.1.80 and 5.9.9.

Base weaknessOWASP Top 10 A07:2025: Authentication Failures (opens in a new tab)
The product does not validate, or incorrectly validates, a certificate.
Architecture and Design · Implementation
Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
Implementation
If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
