update for python-aiohttp","details":"This update for python-aiohttp fixes the following issues\n\n- CVE-2026-22815: insufficient restrictions in header/trailer handling can cause uncapped memory usage and a denial of\n  service (bsc#1261320).\n- CVE-2026-34513: unbounded DNS cache can cause a excessive memory usage and lead to a denial of service (bsc#1261321).\n- CVE-2026-34514: `content_type` parameter manipulation can lead to header injection (bsc#1261322).\n- CVE-2026-34516: response with excessive multipart headers can use more memory than intended and cause a denial of\n  service (bsc#1261329).\n- CVE-2026-34517: large multipart form fields read into memory without size check can cause a denial of service\n  (bsc#1261331).\n- CVE-2026-34518: retained `Cookie` and `Proxy-Authorization` headers when following redirects can lead to information\n  disclosure (bsc#1261332).\n- CVE-2026-34519: response `reason` parameter can be use to perform header injection (bsc#1261334).\n- CVE-2026-34520: improper character handling by C parser can lead to header injection (bsc#1261335).\n- CVE-2026-34525: multiple `Host` headers allow for potential security bypass in proxy servers (bsc#1261343).\n- CVE-2026-34993: loading untrusted input in `CookieJar.load()` can lead to arbitrary code execution (bsc#1267471).\n- CVE-2026-47265: cookies set with the `cookies` parameter on requests are sent after following a cross-origin redirect\n  and can leak sensitive data (bsc#1267561).\n- CVE-2026-50269: improper validation of user-controlled strings allows for CRLF injection in multipart headers\n  (bsc#1268398).\n- CVE-2026-54273: no limit in the HTTP/1 pipelined request queue can lead to excessive resource consumption\n  (bsc#1268543).\n- CVE-2026-54274: incomplete websocket frame payloads can bypass memory use limits and cause a DoS via excessive\n  resource consumption (bsc#1268544).\n- CVE-2026-54275: `server_hostname` TLS SNI check bypass when an existing connection is reused (bsc#1268549).\n- CVE-2026-54277: `max_line_size` bypass when using the optimised C HTTP parser can lead to excessive resource\n  consumption (bsc#1268556).\n- CVE-2026-54278: unread compressed request bodies can bypass `client_max_size` during cleanup and cause a DoS\n  (bsc#1268559).\n- CVE-2026-54279: host-only cookies become domain cookies after `CookieJar` persistence (bsc#1268560).\n- CVE-2026-54280: payload resources are not closed correctly when a client disconnects in the middle of a write and\n  can cause resource starvation (bsc#1268561).\n","affected":[{"package":{"name":"python-aiohttp","ecosystem":"SUSE:Linux Enterprise Module for Public Cloud 15
