An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-55855 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mariadb (Bitnami): affected all versions; fixed in 3.2.4, 3.3.3, 3.4.6, 3.5.3\n- mariadb (npm): affected all versions; fixed in 3.2.4\n- mariadb (npm): affected all versions; fixed in 3.2.4\n- mariadb (npm): affected from 3.3.0; fixed in 3.3.4\n- mariadb (npm): affected from 3.3.0; fixed in 3.3.4\n- mariadb (npm): affected from 3.4.0; fixed in 3.4.6\n- mariadb (npm): affected from 3.4.0; fixed in 3.4.6\n- mariadb (npm): affected from 3.5.0; fixed in 3.5.3\n- mariadb (npm): affected from 3.5.0; fixed in 3.5.3\n- mariadb-min (Bitnami): affected all versions; fixed in 3.2.4, 3.3.3, 3.4.6, 3.5.3\n- mysql-client (Bitnami): affected all versions; fixed in 3.2.4, 3.3.3, 3.4.6, 3.5.3\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-55855/ (Markdown: https://insights.sbomify.com/CVE-2026-55855/index.md)","id":"CVE-2026-55855","markdown":"https://insights.sbomify.com/CVE-2026-55855/index.md","name":"CVE-2026-55855","record":{"aliases":["BIT-mariadb-2026-55855","BIT-mariadb-min-2026-55855","BIT-mysql-client-2026-55855","GHSA-g5xc-5w98-jfvm"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"MariaDB Node.js connector","requires_auth":"none","summary":"SQL injection via Buffer parameters in MariaDB Node.js connector when using specific multibyte character sets, allowing data exposure or modification.","user_interaction":"not_required","vuln_class":"sql_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"},{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. Prior to 3.2.4, 3.3.3, 3.4.6, and 3.5.3, MariaDB Connector/Node.js permits SQL injection when attacker-controlled Buffer parameters are escaped client-side under the big5, gbk, sjis, cp932, or gb18030 client character sets. PacketOutputStream.writeBufferEscape in lib/io/packet-output-stream.js escaped bytes without the charset-aware getMbRecognizer logic in lib/misc/charset-mb.js. The server SQL lexer runs my_ismbchar before escape processing, so an attacker-controlled lead byte can consume the inserted 0x5C backslash as a multibyte trail byte and leave the following 0x27 quote unescaped, terminating the string literal and allowing arbitrary SQL. The default utf8mb4 character set and parameters sent through the execute binary prepared-statement path are not affected. Successful exploitation can expose or modify data available to the database account. This issue is fixed in versions 3.2.4, 3.3.3, 3.4.6, and 3.5.3.","ecosystems":["Bitnami","npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"MariaDB has possible SQL injection in Buffer parameter escaping under big5/gbk/sjis/cp932/gb18030 client charsets","id":"CVE-2026-55855","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"sql_injection","year":"2026"},"n_packages":11,"n_references":10,"next":{"headline":"MariaDB Connector/J: Cleartext password disclosure to a MITM on the initial-handshake","id":"CVE-2026-55856"},"packages":[{"ecosystem":"Bitnami","fixed":["3.2.4","3.3.3","3.4.6","3.5.3"],"introduced":["0","3.3.0","3.4.0","3.5.0"],"last_affected":[],"package":"mariadb","purl":"pkg:bitnami/mariadb","source":"BIT-mariadb-2026-55855"},{"ecosystem":"Bitnami","fixed":["3.2.4","3.3.3","3.4.6","3.5.3"],"introduced":["0","3.3.0","3.4.0","3.5.0"],"last_affected":[],"package":"mariadb-min","purl":"pkg:bitnami/mariadb-min","source":"BIT-mariadb-min-2026-55855"},{"ecosystem":"Bitnami","fixed":["3.2.4","3.3.3","3.4.6","3.5.3"],"introduced":["0","3.3.0","3.4.0","3.5.0"],"last_affected":[],"package":"mysql-client","purl":"pkg:bitnami/mysql-client","source":"BIT-mysql-client-2026-55855"},{"ecosystem":"npm","fixed":["3.2.4"],"introduced":["0"],"last_affected":[],"package":"mariadb","purl":null,"source":"GHSA-g5xc-5w98-jfvm"},{"ecosystem":"npm","fixed":["3.2.4"],"introduced":["0"],"last_affected":[],"package":"mariadb","purl":"pkg:npm/mariadb","source":"GHSA-g5xc-5w98-jfvm"},{"ecosystem":"npm","fixed":["3.3.4"],"introduced":["3.3.0"],"last_affected":[],"package":"mariadb","purl":null,"source":"GHSA-g5xc-5w98-jfvm"},{"ecosystem":"npm","fixed":["3.3.4"],"introduced":["3.3.0"],"last_affected":[],"package":"mariadb","purl":"pkg:npm/mariadb","source":"GHSA-g5xc-5w98-jfvm"},{"ecosystem":"npm","fixed":["3.4.6"],"introduced":["3.4.0"],"last_affected":[],"package":"mariadb","purl":null,"source":"GHSA-g5xc-5w98-jfvm"},{"ecosystem":"npm","fixed":["3.4.6"],"introduced":["3.4.0"],"last_affected":[],"package":"mariadb","purl":"pkg:npm/mariadb","source":"GHSA-g5xc-5w98-jfvm"},{"ecosystem":"npm","fixed":["3.5.3"],"introduced":["3.5.0"],"last_affected":[],"package":"mariadb","purl":null,"source":"GHSA-g5xc-5w98-jfvm"},{"ecosystem":"npm","fixed":["3.5.3"],"introduced":["3.5.0"],"last_affected":[],"package":"mariadb","purl":"pkg:npm/mariadb","source":"GHSA-g5xc-5w98-jfvm"}],"prev":{"headline":"MariaDB has Cleartext Transmission of Sensitive Information and Insufficiently Protected Credentials","id":"CVE-2026-55854"},"products":["mariadb-connector-nodejs"],"published":"2026-08-28","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-31","vendors":["mariadb-corporation"]},"summary":"SQL injection via Buffer parameters in MariaDB Node.js connector when using specific multibyte character sets, allowing data exposure or modification.","url":"https://insights.sbomify.com/CVE-2026-55855/"}
