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: None: The vulnerable system can be exploited without any interaction from any user.
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 6 Aug 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 5 Nov 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

AI-suggested

Upgrade dgraph to version 25.3.8 or later, where this vulnerability is fixed. Patch status is confirmed by the vendor advisory indicating the fix in 25.3.8. No additional mitigations are specified.

Description

CVE-2026-63637 is a high-severity vulnerability in the open source distributed GraphQL database dgraph-io dgraph. Versions prior to 25.3.8 improperly handle regexp filter strings in GraphQL queries, allowing injection of DQL operators. This can lead to unintended data disclosure and unauthorized modification or deletion of nodes. The issue is fixed in version 25.3.8.

Impact

Successful exploitation allows an unauthenticated attacker to inject DQL operators via crafted GraphQL query or mutation filters, potentially leading to unauthorized data disclosure and unauthorized modification or deletion of data nodes. This compromises confidentiality, integrity, and availability of the affected database.

Summary

Dgraph versions before 25.3.8 contain a vulnerability where the function maybeQuoteArg in graphql/resolve/query_rewriter.go fails to properly quote or validate the /pattern/flags form in regexp filter strings. This improper neutralization of special elements in data query logic (CWE-943) enables crafted GraphQL queries or mutations to inject Dgraph Query Language (DQL) operators. Exploiting this flaw can disclose unintended nodes and expand the scope of modification and deletion operations beyond intended targets. The vulnerability has a CVSS 3.1 score of 8.6, indicating high severity. The issue is resolved in version 25.3.8.
